In Manhattan, it's mostly bike couriers who go the wrong way. When I cut across one short block the wrong way because it's convenient, there have been a few pedestrians who've called me out on it.

There are also frequently bikers on some busy avenues when there's a bike lane a block over, which is also just laziness or failure to plan ahead.
