As an irrational New Yorker who’s paid thousands of dollars in those evil yellow parking tickets, I’m for this and anything else that reasonably makes a traffic cops life more difficult and unfair on the job.
You are for punishing the one traffic cop complaining that, although you get tickets, the family of cops don't? Just because you don't like traffic cops in general?
If it helps, making it so that cops and their families are no longer immune to traffic tickets would make it so they tighten up the rules on giving tickets in general. So this guy is very directly fighting to get you fewer tickets.
