not really, on nascar they are going about 60 miles per hour on indy, and on the short-tracks even slower i think.
the rules will change in that direction (pit-limiter speed), with an addition of reducing pacecar length (laps) and a tire restriction to R2 (so they heat up faster when they are cold). but only on the kyoto oval layouts. we also might think about a reasonable MAXIMUM speed under Caution, which might prevent crashes from closing up cars. i will give that information out when the admins and me discussed it.
