1) Toyota has tested and retested the Prius in question, and each time they pressed on both the gas and the brake, the engine was killed by the computer, and
2) The CHP officer that chased the guy down said "'When I saw him, I could smell the brakes,' said Officer Todd Niebert, a 14-year CHP veteran. 'I could see his brake lights coming on.'"
If the brakes were coming on, the engine should have died. If it didin't there was a computer problem.
If the brakes were coming on, the engine should have died.
No, the engine would have dropped down to idle, not died. But given that he "depressed the brakes and accelerator about 250 times", I suspect that every time he depressed the brakes, it tried to close the throttle, but he would release the brakes and keep his other foot mashed to the floor on the accelerator. So, he just repeatedly mashed his right foot on the gas, and would mash the brake pedal periodically with his left foot so that it looked like he was trying to stop, and so that he could get the brakes good an hot in order to fool the cops (and the gathering throng of media drones) into thinking that he really had a problem.
If Mr. Sikes already messed up the brakes what else can you expect?
You’re operating under a false assumption & clearly do not know how the Prius braking system works. Hint, it doesn’t work like a normal car. Read up some & you’ll change your mind, I think.
