Let me get this BS straight:
By this logic, if I am to go out onto the Garden State Parkway, with no helmet (Illegal in NJ) and smack my bike into a bridge at 180, my wife can sue the State Troopers for not pulling me over?
What a load of crap.
Since she's insisting that the local cops never enforced the speed limit, they should hand her a bunch of tickets to make up for all the times they "Looked the other way." That should take care of it.
