Dumbest thing I've ever done was put a remote start on my 5-speed car without a neutral safety. Yep, you guess it. Forgot I left it in reverse to remove my stereo. Hit the little button, heard tires screeching and then a loud boom. I walked outside to find my Mustang parked halfway inside my shed.
Ya, that's pretty dumb alright.
Could be the worst i've seen so far, lol.
