they usually honk at you and tell you to move along. that's what happened to me, except i parked at a 3-way intersection along the curb, so the traffic that was coming at me would have to make a left turn. the cop was making a left turn, so he couldn't just stop and make sure i moved... he honked and i was supposed to move, except i took my time and it didn't seem he looped around the block to come check that i was gone
