Welcome to the forums Karl, hope you stick around and dont pull any burntrice's on us.
I'm not going to tell you how stupid it was weaving in and out of traffic like that though, because i'm assuming you've already realized how dangerous it was to not only you but the people around you. Good luck in future races but next time make sure it's somewhere secluded so you dont endager yourself and others and you can continue posting here.
