This is probably my biggest issue with PD. The only good chase I've had ended in me getting arrested, but it was fun because there were like 6 cruisers chasing us (maybe overkill but whatever). Other times involving their personal vehicles it's never been fun because they just outrun you.
It's also a sort of uniform. Being undercover is one thing, but being just a regular officer patrolling in his fancy sports car is ridiculous. The cruisers at least let criminals know they're about to deal with police, but seeing a random comet roll up should never make me think "is that a cop?"
