Errrm what? Good cops are nothing more than experienced crashers. I know this because I'm some what of an experienced crasher from when I was 13-15 years old playing on Demo S1 and early days of S2.
Pick your target, observe environment, learn your targets basic driving strategy, and make for an attack that won't get you banned.
Of course being a pretend cop it's your pretend job to pit maneuver and damage or disable the other persons car, so you don't worry about the banning aspect of it which then makes you a bit less cautious and well mainly just a crasher looking for a fix.
It's not necessarily a bad thing, 95% of the fun for me on a cruise server is escaping the cops.
End of the day.
Racing requires more skill than any form of cruising.
If you wanna kick back mess around and talk shit then yeah go cruise.
