In Live For Speed we live, in reality we die - www.liveforspeed.net

i know it should be more like "we live in live for speed and die in reality" but it doesn't sound so good IMO

Yeah, I agree, this issue is very delicate, as the wear is affected by one very unpredictable factor, the driver. And the data wouldn"t be much of use...

Forbin: Of course I CAN do that. But it is fairly time expensive...

It would be very helpful for me, as car setuper, to know how much rubber did I leave on surface in one tick (in average per lap/sector/race). Why do I want this? I would use it to estimate how gentle/harsh my setup is to the tyres and if the car can make whole stint in long race.
And of course for experimental purposes. We could play with tyre pressures, rollbars and very precisely observe how they affect tyre consumption.
There could be however one downside, amount of logged data would grow, like one byte for each spot every tick (???, no idea, I am not a coder, so just guessing)
