Most is Cobra 11: Crash Time. The voice acting is horrible and there's no free roam (unlike CT2 and CT3) but that game is great fun and the police cases are well thought out. Least would be World Super Police. Basically super powered police cars with guns on them fire at other super powered bad guys vehicles, with guns on them. It tried a system where you could put other police units in formation, which was interesting - until you had to change lane and hit their vehicle. And all the characters were stertypical. Men were 6ft something with a tan complexion, rippling muscles through their uniforms and sharp haircuts. While the women were all about 5ft 7 with breasts so large the uniform barely makes it to their neck. And all uniforms appear to be skin tight, since muscles are extremly obvious...
