I know I mentioned it before, but seems like if a suicide knob was illegal, could this description of making a turn also be? My bro and I were in a VW Bug in the Winter with snow on the streets. The emergency brake is in question to be used legal to do a 180 degree turn and then shift from forward gear into reverse and give it a lot of throttle. Meanwhile looking over the shoulder through the rear window and keep going in a line loosing no speed or control. You see when the emergency brakes are not self adjusting and one side of the rear drums grabs move than another, then you can pull the emergency brake lever and do 180's. Me in the passenger seat, I watched as I was actually partly more forward in the forward motion as my bro. The snow bank by the curb I was moving away from and the whole vehicle spun counter clockwise. Another one of these 180's and the gear quickly went from reverse to 2nd after the clutch was let go and throttle up. No one was around much so I guess that makes it legal!
