The problem with this is if it’s a long enough line, there could be a persom trying to get into a turning lane and they can’t because you have a big ass gap between you and the car in front. That means the person could miss their light because they can’t get over.
It’s fine if you look behind you and you’re not cutting someone off from a light or turning.
I agree with the gym. I hate being in the environment of the gym, way too many people and I hate working out but if I could do it, it would solve so many problems.
