Okay, I've come to a conclusion... I'd have more fun doing my taxes, than continuing to run this challenge.

That Miata needs twice as much power, three times shorter gearing, and four times stiffer suspension... then it might be slighty more fun to drive at this course than the 1 hp Benz Concept Motor Carriage. Now, I don't think it's the car alone... it's just that there is ZERO rhythm to this track in this car. There's a 3 lap challenge in the game where you have to drive slower, softer, muscle cars on this course, but for some reason the corners just seem to flow into each other in that car.... but not at all with the Miata. I had more fun in the 15 laps I ran at Sears Point than in the 200 I've run at Seattle.
All I know is, the only way I'm going to get faster is by simply throwing the car through the corners another 200 times and getting lucky and not hitting the wall or sliding too much and eventually get a decent time. But the challenge is just way too boring to run for another 6 hours.
So here's my best time. I'll even post the video in a bit so you can tell me where I can improve on this lap. Not that I'm going to try anymore... at least not tonight... and probably not tomorrow, since I think I'm going to make plans to get a root canal on a perfectly healthy tooth
for fun instead.
<-- Tongue firmly in cheek... but serious about not trying for a faster time.
I'm gonna go play rFactor instead. V8 SuperCars at Trois Rivieres FTW!
