From server name, carribean cruise servers are a split from a concept called 'city driving', where people drive around for the sake of driving around. I cant defend the concept or explain it well i'm sorry ot say. There's also servers marked drift where racing doesnt happen, the idea there is to spin the car and, well, spin. There's the odd other server that's not for racing, but basically if it says cruise, city driving, or drift in the name, then your amazing throttle balancing skills wont be appreciated...
