steering wheel lock normally only engages if there is no key in the ignition.
not when the key is in the off position.

But when the engine cuts out, power steering goes too.. and quite often it will feel like steering lock is engaged because the wheel suddenly isn't powered anymore...

Langers, I think you can cross Performance and Safety off your lost of positives for drive-by-wire. Maybe Economy too since the management systems for all that are way more complex (read: expensive) than a simple throttle cable and spring-loaded butterfly valve.

So you have to ask... is sacrificing those other 3 aspects worth it for the extra 5-10mpg?

Sounds smart. Then again I guess your head has been damaged quite a bit in the 100 fights you have been in.

Dude you realize you're quoting all kinds of different posters and addressing me?

Maybe you hit your head! :D

BTW- ANOTHER prius went run away today!!!

The prius doesn't even have a key does it?

Hold the shift lever at the "N" position for three seconds, voila! Neutral!

....putting a forward moving Prius into reverse puts it into neutral, as does putting a rapidly reversing Prius into drive as also does pressing the "park" button above 7 mph.

WOW! :eek::eek::eek::eek::eek::eek:

That would surely be obvious to me! NOT!

Is this in the owners manual?

"pressing the park button"? Is tapping ok? or do you need to press for 3 seconds?

Are there any reports of throttle problems outside of the US?

m21sniper 03-10-2010 10:48 AM

I doubt they sell many of these gay hybrid smug mobiles outside the US. What's more, most of the rest of the world uses manual transmissions.

We're FAR beyond just sticking pedals now. I'm seeing a car (the entire Toyota line, really) that has WOEFULLY UNTESTED software that is resulting in "unwinnable" situations for the operators of said vehicles.

If i was the US Gov't i'd order every single car on the road reprogrammed and/or redesigned to give MANUAL over-ride of brakes, steering, power on/off.

This is insanity.

"With 590,000 sales in North America, this represents the biggest market for the Toyota Prius, followed by Japan with 315,000 sales and Europe way down at 100,000 units."

TGTIW 03-10-2010 11:27 AM

Ok, so a majority is sold in the US, but I've yet to see a report of the problem outside of it.

That would make sense. In the US, there were not many models competing in the 40+ MPG class, at any price. In Europe, there are many many standard autos which achieve 40+ mpg. Also in Europe, diesel is not taxed as much as gasoline, and the hybrids are gasoline.

svandamme 03-10-2010 11:38 AM

if it's 2 :1 ratio with Japan, and 6:1 with Europe..

How many "events" have there been with Priusses in the US?
at least 20 , right?

So statistically that would mean 10 in Japan, and 4-5 in Europe would have had to happen if we're talking about the same car.

Yet so far, none outside the US.
Do they have a different firmware in the US?
What else is different?

TGTIW 03-10-2010 11:41 AM

Driver education.

svandamme 03-10-2010 11:43 AM

driver education wouldn't stop it from entering the news with a title of "my car went nuts, but i managed to keep it together"

flatbutt 03-10-2010 11:49 AM

luv my manual transmission. BTW seems to me every motorcycle I've ever ridden had a master kill switch as does my current ride. seems to be a prudent bit of simple engineering.

"Thousands of incidents" is what i have seen reported over and over, and 34 deaths.

despite the MSM having a field day with this, there's obviously a serious issue that Toyota needs to get serious about.

There are differences between the US and Japanese cars, optimized on how the cars are driven. I think the US cars are setup more for highway speeds. I don't know if the Euro version is similar to the US model, Japanese model or if it is also different.

flatbutt 03-10-2010 12:06 PM

that makes sense to me James. I would expect German Toyotas to maybe have a similar setup to the US.

svandamme 03-10-2010 12:10 PM

ok , so thousands... that makes it even weirder that there just haven't been any issues with them cars outside the US...

Surely Tohyota should know what they do different for US cars!?!
All the have to do, is filter out whatever is in the throttle/brake system... And work from there...

Why hasn't anybody demanded a list of changes? wasn't the CEO in some congressional hearing ?? didn't anybody ask him these questions??

flatbutt 03-10-2010 12:11 PM

Stijn that would require our congressional members to do something more than grand standing.
