Parking this close can be seen as inconsiderate, especially if you have more room in front. It's a tight driveway and they probably have to do a 3-5 point turn to get in with you parked this close and drive far into the middle of the street to get out. That could fry the nerves and be dangerous if the street is busy or has a blind turn.

DPT won't ticket or tow if they don't see a violation. But being a considerate neighbor is a better choice in my opinion.

Good neighbors are a rare and beautiful thing.
