Last spring, driving in Boston, in my Mercedes with PA plates for crying out loud, I went thru a 5 point intersection going stright from a left hand turning lane. On the other side of the intersection, unseen from where I started because it was on a hill, there was waiting 2 or 3 police cars and maybe 5 police motorcycles and they were pulling cars over left and right.
The police had me dead nuts and yet by just being normal and polite and having my Firefighter/EMT stuff in sight, I ended up with just a paper warning.
I think I told about 5 people total about this incident.
