I agree with the use of pit limiters to help regulate the field prior to a start, but is not using it up to a certain point really worth a drive through penalty? I can see if someone doesn't use the limiter and causes a spin or damage to another car, there must be a penalty of some sort. I think the limiter should only be mandatory when every car is on the front stretch and the steward is within a range of time where he can release the field, not in an area like at Aston North where after the last sector split there are some extremely tight corners that may require the normal use of brake/throttle to adjust to what's going on around you.
