I just got the came a few days ago, and it was fun at first but now I got stuck and I don't know what to do. I completed the first season with the small go karts. I thought I was supposed to start 250cc go karts, but I never did. Well, that's what it says by my name, but I never started it, and instead I'm racing something that looks like a Porsche. I thought that might be fun, but now I'm stuck because it is a lot harder than the go karts so I keep going off the track or if I try to slow down everyone passes me up. If I go end the session it says that it will put me in the next session, so I'm not sure what to do next?
