What if the tickets are for parking or other infractions that have no real bearing on safety? If you think this is about safety then you are sadly mistaken.
That depends on the specifics of each parking tickets. Tickets for parking in places where cars are supposed to be (fire lanes etc) are safety related. City parking policies are also generally tied to preventing congestion and dissuading people from driving, both of which are safety-related.
Are you serious or just being punctilious? At this point I'm taking you to be proposing that throwing people in jail for unpaid parking tickets is in the interest of public safety?
By your own logic public safety is served if you park anywhere you want (including fire lanes) but can afford to pay the tickets.
I'll try to keep civil here, but your attitude reflects an utter lack of compassion.
