Todd: I believe he is talking about if it so happens that the accelerator sticks on the Smart, if there is any way to counter it. Which is why i said that popping it into neutral probably wouldn't be the greatest thing for the engine. Maybe if you were to pop it into neutral and turn the key off as fast as possible.... but i dunno.
Remember, it's a manual transmission. Any time you are stopped, the clutch will be disengaged... at that point, it doesn't matter if the transmission is in gear or neutral, there will be no power to the wheels.It seems to me that I read somewhere that when you're standing in a light, and you press the brakes real hard, the transmission goes into neutral.
