The main issue here, seems to be the possibility of driving backwards in HL mode.
Ok, imagine this: I hotlap a LX4/6 with the current system a) at the start of the HL I accelerate with significant amount of wheelspin and stop the car when the rear wheels don't spin anymore and I repeat this procedure many times, b) then I warm the front tires by turning full lock in corners at the same time accelerating, so just before the actual HL starts I have prewarmed tires. I assume you, DEVIL 007 are gonna say that this way is "unrealistic" too, so what do you suggest? I can't brake before the actual HL or I can't turn the front wheels fully left and right?
I could agree with using prewarmed (to one FIXED temperature) tires on BF1, FXR, XRR, FZR, and removing the bacward driving option.
