Just because the cops aren't/might not be doing their job doesn't mean that your action is right or legal. I had a conversation a short while back with a person riding a motorized scooter on The Pinellas Trail here in Pinellas County. Part of his "logic" for riding on the trail is that he has been seen by the police plenty of times entering/exiting the trail and none of them have ever said anything to him. So he figured that it was "alright" for him to be riding his motorized scooter on the trail.

Another part of his "logic" was that it was "safer" for him to be on the trail vs. riding on the road/over the bridge with the other traffic. The problem is that he failed to take into consideration that he was now placing the pedestrians/cyclists who were using the trail in the same danger that he was trying to avoid.
