Looking at your notice there probably are some things that make your car unsafe to be on the road. Parking next to the police hummer was asking for trouble (Reminds me of a story my dad once told me - a mate of his wasnt sure his battery was charging, so he light a match to look down the holes. WTF do you think is going to happen?!?.) If you know you car isnt quite right, probably the best move is to make yourself a little less conspicuous?
No one wants to see the police going hard on any cobra owner, but ensuring your not that obvious may ensure we are not all tarred with the same brush.
Cheers
