There is generally no crime for owning a vehicle used in a crime. The violation belongs to the _driver_ and to no one else. Burden of proof can be extreme in US courts.
A hoodie is enough to defeat the drone surveillance, and regardless of what facial recognition technology you use, a jury still has to buy the output of that system.
For drones with less than a 6 foot wingspan that don't require a runway you've got maybe 30 minutes of flight time at a top speed of 30 miles per hour. So unless you know where they're going already you're not going to be able to effectively deploy it in the time necessary to capture them and you can't loiter long enough to track them with infrared.
The helicopter is an insurance policy. When you have a bunch of marked units doing twice the speed limit on a long enough chase they're going to hit something. Those crashes are devastating and lead to eye watering settlement amounts. The helicopter can safely chase most vehicles at almost any speed and the risk of them crashing with any civilian or even civilian property is effectively zero.
Except that the person trying to get away knows that too, so if all they're doing is buying themselves a bigger fine, why are they doing it?
The answer to that could be because they stole the car, or because there's a body in the back, in which case mailing them a fine doesn't work.
Except it's almost never that. The answer is that people are stupid and impulsive.
You also have the problem that if you steal a car and then run from the police the result is that they don't pursue you and send a ticket to the person you stole it from, that makes it a lot easier to steal a car, and then the percentage goes up.
thing is, in Germany and many other European countries there's a mandate to register your place of residence with the authorities in a timely manner (i.e. 2 weeks after moving in).
Americans and Brits don't have that, so "mail them a fine" is most likely going to result in the letter not arriving where it should.
There's strong wording about updating voter registration when you move, but I doubt there's much in the way of actual law. If there is it's basically never enforced as far as I can tell.
