[QUOTE=cannardd If the last corner is wide enough for everyone to get through without having to go 'single file' then it is usually ok, providing the leading cars don't just charge flat-out from the corner exit.

One of the most important factors, in both the safety and 'fairness' of rolling starts is that the front row, who after all dictate the pace once the pace car has pulled off, maintain the same speed as the pace car (by that stage probably 40/50 mph)
until they cross the start line. In the historic series/championships that I look after, we seem to have got that right and it works well.
