I mean, I do. I've had three tickets over my entire driving career, each in a different state, and nothing in the last 10 years. I've also never been in an accident.

But I've been pulled over something like 10 times total for various reasons (registration expired, headlight out, speeding), and because I'm a responsible driver (no infractions or warnings in the prior year or two), I generally get warnings. If warnings were national, one or two of those might have turned into a ticket, and those would probably be fightable in court (but I'm not going to travel hundreds of miles to fight a $100 fine).

How about understanding what an example is?
