Biggest example of this I can think of is Yas Marina. Grass mowing runs rampant here with no stop/slow down penalty. I’m not talking about a car width off the track. I mean they are several yards in the middle of nowhere cutting the turns and getting away with it. Please fix. Quite annoying.
Other locations where this happens frequently:
Indy GP - turn one, last chicane
Sebring - first chicane, last chicane
Spa - first chicane (Yes, there is pavement, but if you cannot hold the correct line you should be slowed.)
Catalunya - Last chicane
These are just what I have seen. Sure there are others that I have not seen. I do not try to exploit, so I would not know.
