Wrong calculation of rolling resistance

[LBodnar]

That is a very sensitive topic. I've burned my fingers already rewriting/fixing the simulation, had to revert to the current code.

Car parameters are fine tuned for the current implementation and the users are expecting certain(current) behavior.

Any changes will require a lot of testing and car parameter fixes. I suggest to create a fork on github if you wan't to experiment with it.

You are using rolling resistance parameters fo=0.013 and K=6.5E-6 that were lifted straight from G.Genta's book http://books.google.com/books?id=yAo-6yQ...&q&f=false (pp.43-44) but somehow dropped a coefficient Fz which is about 4000 (in Newtons.)

I'd then suggest removing the whole rolling resistance code altogether rather then sticking with an outright bug since at the moment the code produces no sensible output.

At current state there is 1 gram of rolling resistance per tyre.

You can fix the bug and set "rolling-resistance = 0, 0" in touring tyre file if you don't want to upset the car models.

I don't understand the desire to keep an obvious bug. Isn't this supposed to be a realistic simulator? :?
