"Unintended Acceleration", Don't Pray, THINK

This morning on the radio, I heard the audio from a 911 distress call that a man placed while driving an out of control Lexus.  This was one of the events which precipated the massive Toyota floor mat recall.  Apparently, his accelerator pedal was stuck to the floor, and his brakes weren't working (he probably boiled them, or perhaps, the brake pedal was obstructed). He called 911 in a panic, and the operator just had time to suggest that he turn the car off, before the man said "We're coming to an intersection... pray!", and that was the end.  The man and his three passengers were killed. 

He didn't need to pray.  He just needed to think.  He panicked, and got himself and his family tragically killed because he wasn't able to use his cars multiple redundant controls.

Suppose your gas pedal is stuck to the floor.  What can you do?

  1. Use your toe to try to lift the pedal.  This actually happened to me once, that a piece of trash got jammed next to the pedal, and I had to physically pull it up to free it.
  2. If that doesn't work, put your car into neutral.  Then use the brakes.
  3. If your normal brakes won't work (they're cooked, or loss of vacuum) you can use your emergency (aka parking) brake to slow your car
  4. If all else fails, kill the power to the engine by turning off the key.  If you don't have a key but have push button start, no big deal.  On many systems, pressing and holding the engine start button will force it to stop.
So there are 3 different ways to stop your car from accelerating: transmission, emergency brake, engine stop.  It's a shame that the 911 caller couldn't remember any of them.
