There should be some kind of laws around drive thrus, their capacity, and blocking roads. Unfortunately since there aren’t any yet i doubt a cop could actually ticket anyone. Plus a cop is just as happy to wait in the line and block the road as well, because that has been normal and business as usual since drive thrus have existed.

What is really frustrating is try blocking those same lanes as pedestrians or cyclists waiting in a line and suddenly everyone will tell you how unsafe and rude you are.
