I don't know how many episodes of World's Wildest Police Videos you've seen, but police can already force you to pull over anywhere, at any time, and for any or no reason. Spike strips, PIT maneuvers, etc. Letting them pull you over with a remote command would be a huge improvement--high speed chases are unsafe for all involved and (due to frustration and adrenalin) increase the risk of police brutality.
Of course, with computer-controlled cars, you can eliminate traffic infractions and hence most if any need for police to pull you over anyway.
