Yes please

Quote:My thought is that it wouldn't be measured at the drive wheel, because then you would get crazy results when you're peeling out. I don't remember that happening in real life, although it's not like I've tested it very thoroughly.

Tested-thoroughly, and yes it does. Speedometer spikes are a good indicator of a tire(driven) comming lose, good real life indicator in ice/snow. ice and snow??

Another thought, tire smoke comes from heat, so there is a delay from loss of traction to smoke but it would be a nice addition also.

So which tire should I use? FL, FR, RL, RR?

Good point about the smoke. Currently it just generates it whenever there's a large traction loss, but you're right, there should be some thermal inertia... things have to get hot before they smoke.

I say get the speed from somewhere upstream from the wheels. The best place is probably the transmission output. That will still give you the same reading as the wheels, the speed will still spike if you burn out, etc. If you want the reading to be wrong when wrong-size tires/wheels are used, then we'll need something in the car definition file like "stock-wheel-radius" that can be used to calculate speed no matter what changes are made to the actual wheel values.

edit: about tires, heat, smoke, etc....at some point it'd be nice to make the tires "wear" and have this be dependent on how much abuse you give them. I don't think it should necessarily be a perfect physical model of tire wear, I'm sure there's some way to approximate what percentage of tread is used in certain time quantums and under certain conditions somehow...

It's on the output shaft of the transmission, on either wheel would disregard the other drive wheel slipping.
