They have done automated enforcement a few times and it always sucks because the systems don't use discretion.

Someone going 40 in a 30 and swerving around other cars gets treated the same as someone going 40 when the road is empty. Someone slowing to 1-2mph before safely rolling through a stop sign get the same ding as someone blowing through it at 30mph.

If AIs can somehow learn how to take all this footage and enforce the spirit of the law (citing dangerous driving) instead of the letter I will fully support it.
