Hope it's a bit easier to keep the cops on your tail in NFSMW2. Used to be pretty hard to get upto a 3 star chase without accidental killing all the cops. My favourite part of the game was simply just hooning around for hours trying to get in the longest chase possible.
Also a lot more cops would be good too, it should be impossible to outrun them all at a full star rating without hitting one of those hazard zones and quickly ducking into a safehouse.
One last thing I'd like is that if you land on top of a cop car they don't bust you while hanging there and give you a bit of time for your car to slide off before it starts the countdown. Or at least try to roll you off their roof and land you upside down for the bust.
I liked getting in massive head on crashes but the cop cars were like tanks when hitting them from the front, while mine would flip around like a rubber car. I even landed with my car pointing straight up in the air vertically at one time, got busted like a rocket ship.
