Default Runaway SUV bs

I call total BS to these "runaway" vehicles. Totally fabricated. Too many safety systems. If it was "Floored" and he only got to 100 mph in 10 miles in a BMW, that alone is crap. I thought BMW came with run-flat tires? Mine did.

My take..guy owed car payments he couldn't make.

15 minutes of fame.

I heard this on the radio today.

My first thought was, obviously, TURN THE KEY OFF!!

Giving benefit of the doubt, put it in neutral, dumb-ass! Or, maybe hit the brakes?

Some people shouldn't be driving!

I couldn't understand why he didn't turn off the key

So many legitimate questions, so little info. Do not believe anything from the news.

There was a group that did a study on this a while back and determined that, in every car they tested, the brakes easily overpowered the engine. So even with an engine that has "run away" and is floored, the brakes will bring it to a stop without issue.

You are correct for vehicles at stop or slower speeds, but the tests I remember reading some cannot if the vehicle is already at a high speed. Too much energy in motion plus full power from engine would cook the brakes before vehicle would stop.

But as others have said, put it in neutral. Turn key off (or push/hold start/stop button if no key).

Haven't there been examples of this with analog driving? Accelerators jamming, etc?

There's only been 2 types, mechanical and digital "fly by wire". Mechanical, it WAS a problem. Usually a broken return spring. We put a bracket on race cars to pull the throttle closed. Digital..there's so many checks and balances and over-rides it's hard to imagine. Plus..won't go out of gear? Sure, that's electric too, but.....

The worse mechanical one I am aware of was from a broken engine mount that would allow engine to rock pulling throttle open. I think it was what may have kicked off the concept of a recall... a number of decades ago.

Obviously you people are not wearing enough tinfoil to receive the transmission of facts the mass media keeps hidden. Move along......

Audi 5000 started it all..

Weren't the pedals offset to what Americans were used to and little old ladies were killing the husbands pulling up to the garage..?? Or women running over their kids?

The news and 60 minutes in particular was relentless in placing Audi to blame. It was my first dose of fake news!

IIRC, that was the start of the brake/transmission interlock system.

Turn off the ignition, put in neutral, jam the breaks and hope for it to slow down enough to put it into a wall. My other questions would be, since the cops were in touch with him why didn’t they suggest these things? Or did they? They used stop sticks and ended it with a pit maneuver. Roll down the damn window and put it in the canal. Get a SWAT member to put a bullet in the radiator. Ponch and John would have figured this out...

Factory ALWAYS used 2 concentric return springs. Even Chevy and its motor mount issue didn't have throttle problems. Race cars often had issues from backyard engineering.

Drop into neutral is best bet in the situation.

Turning it off probably makes it worse, you lose power brakes, power steering, and possibly lock the steering wheel.

Are you saying a broken motor mount can't cause a stuck open throttle?

Google search it, not unheard of in the "old days" on production cars. Of course back then everyone just put in the clutch or popped it in neutral.

Brakes MAY be able to overcome the engine, but you get one chance at it. Most brakes are vacuum boosted, and the booster stores enough vacuum for one or two applications. Then pedal gets had to push.

if engine is at full power, it is not making vac. So if throttle is really stuck open, and you push the brake and hold it, should be able to stop. But if you try the brake a couple of times, vac is gone you will really have to stand on it to stop. All the while, brakes are heating up making them even less effective.

The Toyota thing was bizarre as to stop the engine, apparently hitting the start/stop button would not do it. You had to hold it for a couple seconds (???, or so I think I heard).

Still super skeptical of all of these cases. Probably most are BS or hitting the wrong pedal.

Anyone know if the shifters are now fly by wire?? Or still a mechanical link to tranny?

Not sure what you mean fly by wire, but plenty of shifters - buttons, knobs, the toggle in my wife’s Benz are at least electronic at the user interface.

I do know that if you open the drivers door on my wife’s car while slowly approaching a light to spit because your wife threw your spit bottle out, it WILL jam the damned thing into park... so I guess that’s my plan if it ever runs away.

Not saying that. Just that OE used cable throttle often. We had more problems with mechanical stuff falling apart.

Transmissions are 100% digital. There may be a linkage, but it just shifts electronics.

10 miles or so in a BMW flat out is NOT 90 mph top speed.

The Toyota thing..copycats.

it is a BMW fellas, most likely push to start, no key turning involved. Also probably has one of those weird circle things that you use to put it into park drive neutral etc... or is that Mercedes?

But yeah I call BS on a run away accelerator.
