The online racing simulator
Running Start + something old, probably.
LFS is absolute hell at the beginning of the race. Tires are cold, noobs flourish. It would be practical to have a running start, either manually, by following a pace car, or automatically (similar to GT4) to have the tires pre warmed and no horrid slipping around.

Also, although it may not be realistic, it should be included as an option for more noobish servers, is the option for no collisions. I hate wreckers and the whole race for me thwarted because some idiot taps my bumper and I do 80 barrel rolls.
Rolling starts has been suggested before, few times.

I don't think it will help on T1 crashes on anyway. Tyre heat isn't the issue there and what would happen everyone would be coming to T1 at a faster speed which is doing the exact opposite.
