As for the pit road speeding penalties, it's a well known fact that drivers push the limit and speed in between scoring loops. I doubt this is NASCAR's fault. Drivers push the limit, and there's nothing wrong with that because that's what their job is. Remember, NASCAR gives the drivers a 5 mph window of tolerance.
Totally my opinion, but drivers know track position is important at Pocono and are pushing the limit as much as they can and they're just getting caught today.
If track position is all that important, why would they push the limit knowing that they are going to give up track position?
