i don't see any reasoning behind this
you can go on any highway in NJ and clock 50+ cars going 80+ (now i know the law only apply for the one getting pulled over) so it was your turn that day
the only way the officer knows she was going "a little fast" is because she passed him but what if he was going 55? 45?. i got pulled over for a 51 in a 50 the judge laughed at the ticket. i would just fight it because in the end there's not prove just the cops word in some cases that enough but a traffic needs some evidenced i believe
