So the other day I was driving my 06 kenne bell supercharged gt. I realized I was going the wrong way so about 20 mph I went into 2nd and did a 180. After I spun around and was at about 3 mph I shifted to 1st and my drive belt came off.... This has never happened to me before and I am fairly good at driving and haven't had any problems. Any ideas as to why this happened?
