Mildly horrified by this video explaining how to replace a crystal on a Toyota engine control module to, i shit you not, up the RPM limit.
Now I'm actually curious how *real* fail-safe accelerator pedal would be designed in a pure electric vehicle. Probably should be some kind of resistor/fuse array routed by pedal position inline with current to the motor(s).

Pretty sure they didn't have a real fail-safe...

Soooo, supposedly, the closest thing to a failsafe was that if you held down the start button for 3+ seconds it would kill the engine. That's not a fail safe, but it was an out.
