Maybe but does not the driver stop it after several commands from the officer? I understand his unconscienceness could have been only temporary.

Either he planed to ram the crap out of the guys squad car or he planed to floor it from the starting position and put it in the wrong gear.

The only reason I would believe he wasn't knocked out is because it sounds like the car is reving up and down like the driver was intentionally pressing the gas pedal and letting off several times. I would assume that if you were knocked out your foot would just rest on the gas pedal instead of hoping on and off. In saying that im not sure what the computer program in vehicle would do in a situtation like that, would it detect the abnomily and act accordingly regardless if the driver's foot is pressing the accelerator.
