You guys need a better system for flagging because when the cars are this powerful the least little hit and it's over. How about a 3rd car in the farthest right lane and once everyone is lined up he cuts off his lights for the go? Or cuts them on? You get my drift.
Make a little clip on drag light for the window. Take a AA battery and a suction cup. Surprises nobody came up with this yet. I wan't 20% royalties if anyone makes it. LOL
