Im in a jam.....

like a dead man switch? If it sticks WOT, you can just turn it and go into a spin, enough to stop the forward motion of the tire as the motor is not that torquey. The relay in the burned motor control was a tiny 20A PCB mount relay the size of a Vegas dice, and only 1 little surface mount component let the smoke out. It was an 8 pin chip but that's all I could tell you as it had turned to ash.
