[LAT] Runaway Prius hits 90 mph before stopping with aid of CHP - Page 11

post #101 of 400
Several things I've noticed here.....

If this is truly an electronics problem like people think it is then several issues arise
Since the shifter is electronic, it makes sense that shifting into neutral ISN'T possible during a malfunction
The same could be said of the starter. If the starter is electronic, pushing the button may not work since it relies. on the computer.

Power assist on the brakes is necessary. All braking systems have some sort of accumulator that will keep pressure in the system and allow a limited amount of stopping power before being drained, but once the power assist is gone, so is your ability to stop. Try it with your car the next time you stop. Turn off the key, then step on the breaks. In a few hard pumps, the pedal will become rock hard and that means your accumulator has run out and your stoping power is gone. At this point, only the emergency brake can stop you, but not nearly as quickly as the full braking system can.

Been there done that and it is still possible to stop.

I had a fuel pump die on me while going 50 in a right turn lane, had to break for 3 turns with no power steering and into a parking lot. Got it to stop just fine even though the break was rock hard and took most of my force to apply.

What he said. The brake becomes rock hard but you can still brake. You just need to apply more force, and it will brake slower. I haven't done it at these speeds, but I enjoy cutting the engine when getting in my entryway and I lose power steering and power brakes while parking. It IS possible - just like a car that has none of these.

If the driver had half a brain tho you'd use both the brakes AND the handbrake... and if I had a new car that had these issues I wouldn't hesitate to put the car into the park position.

And this is why people get viruses...

Several ways to fix this

Turn the car off
E-brake
Brake
Shift

Or a combination of any of those. Honestly this guy should be locked up for 5 years and never be allowed to have kids.

again, it may not have been possible to shift the car into neutral or stop the car due to a computer malfunction.

The push button start and the shifter were controlled by a computer.

But knowing how to safely deal with a situation when driving is something you should be able to do, its not like some speciality skills. This toyota issue is known to all now, if you choose to be ignorant when you know its a possibility then your stupid.



Sometimes they are called parking brakes or handbrakes.



Downshifting is a terrible idea for normal driving, it wears out the transmission which costs thousands, brakes cost hundreds. Now if it was a life or death you do what you have to.

Your "slam on the brakes and hope for the best" really made me laugh...what do you think brakes are for?
I mean, that people often hit ice or oil and their instinctive is to put their foot on the brake and use that all the time. People use the brakes all the time, instead of using the clutch to aid in slowing down etc...

EDIT: You yanks drive automatics, my bad!

Yea this is true. I drove a straight drive since before I got my permit up until recently. Around 6 years. It's all I ever drove. When I got an automatic I instantly felt like I had no control over the car and it still feels weird to this day. It's been 8 months. I like the automatic in stop and go traffic but other than that I prefer a straight drive(manual).
