My guess is that most people who think it's just terrible, un-American, etc. that a red-light camera ticket is decriminalized (civil, with no jail) and "how the frick can they make a crime into civil, I thought that was just people suing each other?"...
think it's just outstanding that possession of marijuana in several jurisdictions has been decriminalized (made into a civil offense).
Other traffic laws that carry a civil penalty include parking tickets.
By the way, you do not have the Constitutional right to face your accuser in a civil matter.
