Implying you can spot the drone. Best police drone would simply tag the vehicle and see where it is moving around, then apprehend the fugitive one he settles for a longer period (during the night usually).

You don't need to spot the drone. If they start getting used regularly, the escapees will assume it's there and may try to evade it anyway.

Yes, but how are they going to do that if they can't see the drone? How will they know when they have succeeded? Are they just going to continue driving recklessly until they run out of gas?

Driving evasively seems like a very good way to attract the attention of other officers who might not recognize the suspects' car. Once the cruiser is out of sight, the suspects' best bet would be to "act casual." If the drone can see the suspects then it doesn't matter how they drive, and if it can't see them then driving like a maniac only makes it easier to be found.

Really, to "act casual" in areas with lots of tunnels and trees and other cars of similar make and model and color. Or to get off the road quickly somewhere underground (parking garage?) and leave the vehicle, though that has difficulties as well long term (CCTV being a major one).

Drive until you've got some distance from the police, head underground, then switch to public transport.
