I would be okay with automated traffic law enforcement if police officers were forbidden from making traffic stops for the sort of violations that the cameras issue fines for.

It would turn the most common motoring offenses into predictable fines, rather than gambles where you can get away with it most of the time, but you might get arrested or shot if somebody is having a bad day.

It could also encourage voters to demand that speed limits and road construction reflect the real traffic conditions, ideally reducing the vast stretches of 40mph highways where you'll get tailgated by semi trucks if you're doing less than 70mph.

On the downside, it would make license plate scanning a permanent fixture of most roads, but that's already true in many places.
