I'm thinking with the dire budget situations in municipalities, states, and feds, law enforcement operations that CAN be automated WILL be automated.
Two officers in a car is expensive, and technology gets cheaper everyday.
The flip side of the red light and speed camera issue is nobody wants to pay higher taxes for ever increasing municipal budgets, but we won't tolerate chaos on the roads either.
I don't know about elsewhere, but a local city has stop light cameras, THERE ARE SIGNS warning of their presence, they are STATIONARY, and they still catch people all day long.
Under those conditions, I am thinking folks caught in that town don't need to be driving and endangering me if they are that insulated and unaware of their surroundings. And if there are cheaper ways of zapping them back into minimal levels of consciousness, I am in favor of it.
Put down the cheeseburger, hang up the phone, drop the lipstick, turn off the Ipad, and drive your farking car!
