Also, in the storyline, the characters would say the Downtown area is filled to the brim with cops. Ironically, I don't see any cops about 15 - 30 minutes apart.
It would be really annoying if police in free roam were like in Rivals, where they begin to chase you for sometimes just being parked at the side of the road, and in higher levels, they would constantly slam you and surround you with their supercars that easily catch up to you going 300 km/h.
Free roam police can be left untouched, if there would be bounty spots like in Most Wanted 2005, with a tweak that if you start a chase that way, the police has more aggressive cars.
Currently, you can always take a near-stock car for enjoying chases.
