Mizzthang, I have to echo Michelle, *please* be careful! I've done things like this, but I was a passenger in one photo (Tunnel), and in the other (Gateway) I had the camera on a tripod (strapped securely in) with a cable release...and even then that was a bit naughty!
Having said all that, this is one cool "road' photo, and so crisp! How low slung are those ZX2's? -you look to be at bumper level!
