I am going to retort, this is a BAD idea for a road racing car. and even worse an idea for a rally car. the rule stated above might work in drag racing but that dog does not hunt in any form of motorsports longer then 1320. in REAL racing there is no second chance, an accidental trip of a cut-off could prove disastrous. I want someone to enter turn one at sebring and turn off there engine mid turn, instant wall spot. NHRA apparently is not concerned with cars that cross train. in my opinion another reason not to waste time going straight.
