865300 2010-03-10 05:25:00 I would be interested in knowing,
1/ Why cant you turn the ignition off? You obviously have time to make a phone call.
2/Why cant you put the engine in neutral?

I've been hoping SJ could enlighten us on those points because it does seem rather strange that the simple steps that could be taken to halt the vehicle are not being used.

It is possible that the US and other countries have interlocks of some sort that prevent the ignition switch from being turned off when mobile, and I stress that this is not the same thing as withdrawing the key, which would usually cause the steering to lock. I have also read about one vehicle that requires a button to be pushed to turn off the engine. Weird but apparently true.

The other option of pulling the shifter back into neutral (all these cars are automatics it would seem, which does point to something other than the accelerator when you think about it) but maybe the US and the other affected countries don't allow the shifter to be put into neutral once travelling above a certain speed. Illogical, but possible.

My personal view is that in the majority of cases the drivers are of the 'point and squirt' school of driving and that the real cause is the nut behind the wheel being loose as a goose.

How about it Joe? Let's hear your opinion, you have the knowledge and experience to give some insight. You started this thread and have been unusually quiet since.

Cheers

865302 2010-03-10 09:17:00 Many modern cars don't have an ignition switch any more. It's all controlled by electronics. My guess is the transmission gear selection is too. If the programmers didn't do a good job & not enough safety backup has been built in to the system, then these things are going to happen. My guess is that the big one is yet to come Phil B (648)
865303 2010-03-10 10:27:00 A mandatory emergency kill button on all new cars produced, which (via a direct electrical connection) cuts power to the fuel pump / injectors / whatever would avoid the possibility of this kind of thing ever happening again.

It would be entirely independant of the ECU so programming errors could never be a problem. It could be hidden out of the way and eventually everybody would know about it and it could be an idiot-proof reaction to trouble for those who wouldn't think to put it in neutral, or for some reason couldn't.

I remember that episode, actually to be fair the Prius was driven at full speed, I think the BMW had to change up to second gear at one point lol.

Lets face it like many Toyota's, the Prius is not made for people that enjoy driving, add to that they are one of the most hideous looking cars on the market.

oh its on Youtube

One of the companies that I do work for has a fleet of Toyota's, all are fitted with battery isolation switches, one on the dash and one usually on the front bumper. These are all self installed independent of Toyota.

Isolating the battery of a moving vehicle would kill the motor as well ?

865306 2010-03-10 20:26:00 i love how it took a cop and a loud speaker to tell the driver that they could stop it by turning the ignition off

DUURRRR :lol:

recall the priuses and destroy them for ever existing and recall the drivers licence for clearly not knowing how to operate a vehicle in an emergency

problem goes away :p

the alternator should keep the engine going if the battery is removed from the circuit - unless the alt is dead it would keep going

and having a fuel cut on some cars especially turbocharged ones would be another disaster - if the throttle was jammed open and the engine racing if you were to cut the fuel it would lean out hideously and in a turbo car that would happen ten fold and you would melt the pistons

so now you have a car that has a jammy throttle and a melted engine - aieeeee!
