> Sadly, in California most theft is merely a misdemeanor, and busy PDs do not have time to chase down criminals to give them a ticket. But they sure do like camping out all the time to give people speeding and parking tickets. Priorities!
Speeding tickets make sense. They're putting people's lives in danger by speeding. Driving is the most dangerous thing most people do regularly. Having a set of predictable behaviors saves a lot of lives. People who think that think they're "great drivers" or "everyone else is doing it" violate those norms and create risk.
Speed at which you drive has very little to do with your predictability. "Oh, no, Betty is driving 5 mph faster than me. I'll never know what she'll do next!"
Even if you try to give an example of someone coming up on your left at a 50+mph difference, it's not an issue if you signal and look in your rear view mirror to make sure it's clear. Most people just don't do either.
