Sportsmanship and temptation

A recent episode of the Freakonomics podcast What Do Skating Rinks, Ultimate Frisbee, and the World Have in Common?, talked, among other things, about Sportsmanship in Ultimate Frisbee versus other sports.

Ultimate Frisbee is self-policing. It has no referee: if someone on the field thinks they've been fouled, they call it out, and the two players reach a consensus.

Why don't the players cheat and take advantage of the lax rules and the lack of a referee? Because sportsmanship and honesty is part of the culture of the game, in a way that isn't true in refereed sports like soccer, basketball, tennis or nearly any other sport played professionally. The Ultimate players they interview talk about the culture of the game, the longtime attitude that every player is "morally bound to abide by the rules. The integrity of Ultimate depends on each player’s responsibility to uphold the spirit of the game."

And that's great. But I submit that there's a more important reason: because there's not much at stake in Ultimate Frisbee, compared to football, soccer or basketball.

Ultimate is still a chiefly hobby sport which is only barely starting to get sponsorships and professional teams. I'm not up on the Ultimate scene, but I bet there aren't a lot of millionaire players yet, or a lot of poor kids practicing their frisbee throws as their way out of the ghetto.

To make my point, let me tell you a tale of two autocross classes.

Autocross, if you're not familiar with it, is miniature car racing. You race against the clock, one car at a time, on a course delimited by traffic cones on a large parking lot or airstrip.

There are lots of different classes, so cars race against similar types of cars. The classes cover different preparation levels, starting with Stock classes, where you can't make any modifications beyond tires, shocks and a few other carefully specified items. Next above stock is Street Prepared, where the cars are still more or less street legal (many are still daily drivers), but they have lower, stiffer suspensions, wider wheels, sometimes headers or high-flow mufflers or fancy intake systems. Then above that are Race Prepared, for cars prepped to road racing standards, and Modified, for purpose-built race cars like formula cars.

Autocross, when I was actively racing (and I doubt it's very different now), is almost entirely an amateur sport. There are some sponsorship programs, called "contingency programs", where you can earn a few hundred dollars if you win a big race using the right car, the right tires, the right shock absorbers. Some races throw in modest amounts of prize money, so that at a big national level event a handful of winners might be taking home a few thousand dollars over their travel expenses, maybe ten thousand at the absolute top end. Most class winners don't even make enough to pay their travel expenses.

Curiously, the best contingency money isn't in the superfast, exciting Modified classes; it's in Stock. Why? Because the money comes from manufacturers hoping that someone will see your stock Miata winning the class and say "Wow, maybe I should buy a Miata too!" or "Maybe what my Miata needs is those tires/shocks/whatever."

I ran my Fiat X1/9 in D Street Prepared. DSP is seen as a class for old clunkers -- some of the winning cars besides the X1/9 included the Mazda RX3, VW Rabbit, Datsun 510, Datsun Roaster, and CRX HF. They're all old cars, no longer on the market -- so manufacturers weren't very interested in offering contingency money for them. That was okay -- our cars were fast and fun to drive, we had great competition and a lot of fun. Everybody was friendly with each other -- sure, we were all out to win, but if someone had car trouble, you could bet that everyone would be gathered around the car trying to help. If the problem wasn't fixable, another competitor would offer a ride in another DSP car. I saw that happen even at Nationals -- everybody was intensely competitive, but in a friendly way.

That's not to say nobody ever cheats. Sure, occasionally somebody wanted to win badly enough that they'd make some illegal modification to their car. Sometimes they even got away with it for a year or two before anyone figured it out. But cheating was relatively rare ... at least until contingency money started to edge up into the thousands of dollars instead of just a few hundred. Then you started to see a lot more protests, a lot more engines and suspensions turn down, and a lot more cars found illegal and disqualified. And most of the protests happened in the stock classes.

And then one year at Nationals, I really learned how those big contingency prizes changed the sport. I was running my old Fiat in DSP as usual (actually DSPL, the parallel class for women drivers). A friend of mine was there in a stock car she'd bought just the year before. She'd worked really hard all year, was driving exceptionally well and was widely thought to have a good chance to win her class. (I'm deliberately omitting her details like name, make and class.) We were all rooting for her.

And then one morning, a day or so before her class was scheduled to run, she discovered that one of her brake lines had been cut.

Her brake line! On her daily driver car that she was going to drive 1,500 miles home after Nationals was over!

Fortunately, she found it in time, and lots of people pitched in to help her get the brake line fixed. But it was pretty terrifying to know that something like that was even possible in what I had always seen as a friendly, fun, amateur sport.

I don't know if anything else like that happened in other classes. It wasn't widely talked about; you might not have known about it happened if you didn't know someone involved. They never found out who did it, as far as I know. But there were a lot of protests in the stock classes that year, too -- nobody trusted anyone, everybody assumed their competitors were cheating, and there were engine and suspension teardowns. It all made me glad I was in unassuming (and fun!) old DSP and out of the money.

So, getting back to the Ultimate referee question. Yes, sports that have a friendly, sportsmanlike culture are terrific. But I think -- though I wish I didn't -- that the Ultimate players may find, as their professional league gets off the ground and they attract more sponsors, that the moral code they've taken for granted is partly due to not having much at stake.

Money, or the prospect of it, does something to people. And I'm not sure money and stand-up honest sportsmanship make very good bedfellows.

Watching people weave into and out of our lane while they texted on the freeway (where are all the cops who are supposed to be cracking down on that this week?), Dave came up with an idea: a competition where you drive some sort of course -- start with an autocross course, or maybe add twists like parallel parking -- while simultaneously texting. Your score is a combination of your time through the course, fewest pylons hit, and the accuracy of your texted replies.

He was thinking of a show we used to see at a pizza place we frequented a few years ago, "Cash Cab". The premise: there's a special taxi that drives around New York City rigged with video gear, and if it picks you up, you get a chance to play a "Who wants to be a millionaire" style quiz show in the time till the driver gets you to your destination.

I have to admit, although Dave's combination of Cash Cab and autocross sounded intriguing, it didn't sound like something I'd actually want to do. Although I see plenty of drivers who seem to love the challenge of parallel parking or negotiating rush-hour traffic with one hand (or no hands!), it's not my thing.

But here's a modification that did sound fun to me: you wear a hands-free headset, and while you negotiate the course, someone asks you quiz-show type questions and you have to answer while you're driving the course. You can still use both hands to drive; just not your whole brain.

It's an exercise in concentration and filtering distractions. Can you figure out what part of the course needs your fullest attention, and which parts you might be able to take nearly as fast while thinking about the quiz question? It's a biathlon for motorheads.

The scientifically minded part of me wants to take a little extra time and add a free run through the course for each contestant at the beginning and end of the event, with no quiz questions. That way everybody gets a baseline time for the course, and it's easy to find out how much the distraction hurts our driving. Some studies say that a hands-free phone is just as distracting as a handheld one. Wouldn't you love to find out exactly how true that is for you?

I know it'll never happen -- it's hard enough to reserve autocross sites without the additional complications of an untried event format. But I'd sure love to try it. If any researchers with funding for distracted-driving studies are reading this and want to use the idea, count me in as either a helper or a study subject.

I'm calling it QuizCross. You heard it here first.

Becoming Kaylee: Thoughts on Making and Fixing

A recent Jon Carroll column got me thinking about Making and Fixing.

This was the passage that got me started:

... I took it to Dave up at the repair place. "You need a new battery," he said. Looked like a fine battery to me, but what do I know? I had a second opinion from the guy who wanted to sell me a battery. What could go wrong?

I brooded about this on the way. I realized how much we are at the mercy of the repair people in our lives, and how much we do not know about, well, most things.

At their mercy

That took me back. I grew up with the idea that mechanical things like cars were a little scary, something one doesn't really muck with. This despite the many happy afternons I spent building little balsa-wood gliders with my father. Later, I learned a little electronics, and built little things like a switchbox so my mom could switch between cable and VCR without unplugging anything. But knowing I could handle an X-Acto knife and soldering iron somehow didn't translate to the notion that I could work on anything as scarily mechanical as a car or a home appliance.

When I was just getting out on my own, my car -- a 200SX turbo, my pride and joy -- developed a terrible ticking sound. When I got on the gas hard, it would make this loud tick tick tick tickticktick.

I took it to the mechanic. He listened to the noise and said "Lady, it's your turbo." He said it needed replacement.

I was pretty sure that wasn't right. I had read the turbo spun at something like 100,000 RPM. This sound was more like -- I don't know, a few ticks a second, maybe a few hundred RPM? Shouldn't something spinning at a hundred thousand RPM (let's see, that's ... divide by 60 ... 1667 Hz), shouldn't that make a sort of a whine, not ticks?

I asked the mechanic that. He shook his head. "Lady, it's your turbo. You have to replace it."

I was pretty sure I was being lied to. But what could I do? As Jon Carroll says, "we are at the mercy of the repair people in our lives." I arranged for a replacement. The warranty covered part of it; I still had to pay quite a bit.

And when it was over, the tick-tick-ticking noise was still there. I'd been right -- the noise wasn't coming from the turbo. Somehow that didn't make me feel better.

Becoming Kaylee

I saw a movie some time around then -- some awful movie involving motorcycles, I forget the details -- that had a character I liked. You've probably seen the archetype -- she's been in other movies. You know, the girl-mechanic with the grease smudge on one cheek and the bright eyes. Think Kaylee from Firefly, only this was long before Firefly.

I wanted to be that girl -- the one who never had to put up with mechanics lying to her, the one who'd never get stuck somewhere. She had control over her life. She understood the machines.

But how do you even get started learning something like that? All the guys I knew who knew how to work on cars had grown up in a culture where they learned it from their father or brothers.

I set a goal: I'd do my own oil change. I found instructions somewhere. I bought a crescent wrench -- one of those adjustable things -- and an oil pan to catch the oil, and a new filter. I lay down in the dirt and slid under the car and got the wrench on the bolt and ... it kept sliding off. I couldn't get the bolt loose, and I was rounding off the corners so maybe no one could ever get it loose. Oh no! The instructions didn't say what to do if that happened.

I got in the car, drove to the local mechanics' shop (not the same one that had lied to me about the turbo) and threw myself on their mercy. I said I'd be happy to pay whatever an oil change cost, but I didn't want them to do it -- just please show me how to get the bolt loose. They were super nice about it. They broke it loose (they said whoever did it last way over-tightened it). They took a look at my crescent wrench and told me never to use it again -- that I should stop at Napa on the way home and buy a 14mm box-end wrench. I don't think they even charged me anything.

Back at home, armed with my new 14mm wrench, I got the drain plug off, and the rest of the oil change went smoothly. I changed the filter and put the new oil in and closed up. My hands were shaking as I drove off -- surely all the oil was going to fall out right away, trashing my engine forever. But it didn't.

When I got back, one of my housemates was home. He said "You look adorable." Apparently I had that grease smudge on my cheek -- you know, just like the girl mechanic in the movie. Maybe there was hope!

And you know what? Once I knew how to do an oil change, I found it took less time to do it myself than it did to drive to the shop, drop off the car, arrange a ride home, and all the other hassle associated with having someone else do it.

Beyond oil changes

Doing my own oil change boosted my confidence incredibly. But I wanted to learn more. I wanted to be able to fix things when they broke down.

It was around this time that I took up autocross racing. Of course, a lot of the guys at the autocrosses were great mechanics. I started asking them questions, picking their brains.

My car still made that tick-tick-tick sound -- I'd pretty much learned to live with it since it seemed to be this mysterious thing no one knew how to fix. I asked one of my autocrosser friends. He said "Yeah, I've noticed you have an exhaust leak. You should fix that" He said it like, duh, doesn't everybody recognize the sound of an exhaust leak when they hear it?

What's an exhaust leak? How would I fix it? Turns out it means the gasket between the exhaust manifold and the head is bad. You have to unbolt the manifold and pull it back so you can slip a new gasket in. (He showed me what all those things were so I'd know what he was talking about.)

Normally that would be pretty easy, but on a turbo car it meant disconnecting all the turbo plumbing and moving the turbo out of the way. Eesh!

Another autocrosser, an expert mechanic, offered to help. We did the job. It turned out to be harder than expected. Seems that previous mechanics, probably the nim-nuts who replaced the turbo, had messed up the threads in the aluminum head -- and instead of fixing it right, they'd just taken a stud with different threads and jammed it in. I learned all about taps, and Heli-coils, and other techniques that weren't part of the original plan.

And the noise went away. We fixed it right. Not like the shop that was only interested in screwing another ignorant customer out of whatever they could get.


I still wanted to learn more, and not be so dependent on helpful guys. I looked around for books. Shop manuals and Haynes and Chilton and Clymer manuals all assume you're already pretty comfortable working on cars. I needed something that explained things.

I'd been kicking around the idea of getting a car just for autocross -- some older, simpler car that would be easy to learn on. One option I was considering was a Scirocco, and that put me on to Poor Richard's Rabbit Book: How to Keep Your VW Rabbit/Scirocco Alive.

It was fabulous. It explained everything from the beginning -- what the various parts do, how to find them in a Rabbit/Scirocco -- but it was clear enough that it worked for any car, not just a VW. I inhaled that book. It was my bible for years, even after I gave up on the Scirocco idea. I chose a Fiat X1/9 instead.


Everyone knows Fiat's reputation. The joke is that it stands for "Fix It Again, Tony" (though I always preferred "Fix It Alla Time"). A Fiat would surely force me to learn, fast.

[Colibri, my Fiat X1/9] My new baby, Colibri (Italian for "hummingbird") was a mess of a car. It had been in several accidents. Just about everything needed some amount of work. It was perfect. I loved it.

My first big job was a brake job in the parking lot of a San Diego Pep Boys, Poor Richard's and the Haynes manual in hand, the store handy so I could go in and buy tools I discovered I needed, a pay phone nearby so I could make long-distance calls to my boyfriend when I hit snags. (We were in the process of moving, but the brake job couldn't wait until he was there in person -- and besides, I wanted to learn how to do things myself!) I was there for hours, and used the pay phone several times. But I emerged triumphant -- covered in grime, but with brakes that worked great.

Over the next few years of driving and racing Fiats, I learned how to re-jet a carburetor (and how to do it really fast when a bit of fluff from your sketchy aftermarket performance air filter clogs a carburetor jet when you're stuck in traffic on 101 and the car suddenly isn't getting any power from the primary). I got good at replacing the alternator, doing alignments, working on suspension; I replaced the exhaust system a few times, and eventually the head.

We don't have to be at the mercy of the repair people in our lives.

Fixing and Making

And that brings me to the Maker movement -- because fixing things, very often, is making, and that's something I hadn't realized at first.

I remember watching my master mechanic boyfriend (the one who'd helped me with the 200SX) faced with the problem of a pop-up headlight that rattled. The link that held the light in place was worn from so many years of rattling along potholed roads. The part was available -- but look at it, he said. This will just wear out again in a couple of years. There's no lubrication, no adjustment, no compensation for how the angle changes as the headlight goes up and down.

He redesigned it using a rod end -- a lovely piece of hardware that has a threaded rod (adjustable!) at one end and a nylon-encased ball bearing at the other. It came out far more solid and adjustable than the original ever was. No more bouncing!

Later, when I got more confidence in my own automotive ability, I could do some of that myself. My proudest accomplishment was a set of adjustable spring perches made out of a toilet part from the hardware store. They cost about a tenth as much as the custom spring perches the top-flight autocrossers were using, and worked almost as well. I only wish I'd been prescient enough to have taken photos for a future website.

When you take your car to a mediocre mechanic, like the one who lied to me about my turbo because he was too inept to recognize the real problem, you get the wrong idea. You come away thinking that fixing things is all about replacing one part after another until the customer stops coming back. But real fixers aren't like that. They look at a design and ponder how to make it better. They fiddle with things, and try out new ideas. If they're not sure what's wrong, they set up experiments, just like a programmer does chasing a bug, or a scientist testing a new theory.

In today's world, being a Maker is hot now, while being a mere fixer isn't held in such high regard. But it should be. People who fix old stuff -- who can figure out how to take something broken and make it better than it was to begin with -- not only are creative Makers, they're also environmental heroes. They're our best hope to keep us from drowning in a sea of discarded junk.

I'm still not that good at it. I try to fix my computer stuff when it breaks. I've learned a little woodworking, painting, plumbing and other home-maintenance skills from my husband, who grew up in a culture where most people worked on things like that. (That definitely wasn't true where I grew up.) I don't work on the car nearly as often as I used to in the Fiat days -- I have more money and less energy and free time -- but I try to do enough that I know what does and doesn't need fixing. When I don't know something (which is still most of the time), I google for help, and fiddle with things, and invent solutions, and sometimes I succeed, sometimes not. When I do go to a repair person, I can ask the right questions, and I can tell if I'm being lied to.

Jon Carroll is right, of course. There's so "much we do not know about, well, most things." None of us has time to know everything about everything we own. But that isn't going to stop me from trying. Fixing is just as cool as making ... and maybe they're the same thing, really. And I still want to be Kaylee. Maybe I'm making progress.
