What happens if you get overtaken and they pull in a bit sharpish?
Does it brake suddenly as there's something in range or is cleverer than that?
Same if they pull in and brake test you. Do you end up with a sore neck and brake testing the person behind?
On the BMW Yes, and Yes. tht's the way it's programmed.Does it brake suddenly as there's something in range or is cleverer than that?

The problem with auto anything is that it is fine right up to the time it is not.
Even the relatively simple auto devices on my car such as start/stop and auto hold on the park brake don't always do what they are supposed to, Most of the time no problem if one is quick enough to counter the problems unexpected / temporary failure of these auto devices put you in, but like the joke about the fully automatic air liner, (This jet has no pilot and is automatic so nothing can go wrong go wrong go wrong etc)I would rather not rely on electronic aids any more that I have to.

I guess the mean time between failure rate of these devices stacks up against the human brain fades or lack of concentration of the average driver though. How many accidents are caused by actions so dumb that a computer system would be grounded for doing the same?Even the relatively simple auto devices on my car such as start/stop and auto hold on the park brake don't always do what they are supposed to, Most of the time no problem if one is quick enough to counter the problems unexpected / temporary failure of these auto devices put you in, but like the joke about the fully automatic air liner, (This jet has no pilot and is automatic so nothing can go wrong go wrong go wrong etc)I would rather not rely on electronic aids any more that I have to.
FWIW I have front assist in my Golf and it has beeped a couple of times but never braked for me.

Hi all,
Anyway, merrily driving along yesterday, a Mk5 Fiesta I was following turned left (rather slowly in all fairness) and as it pulled off I accelerated away (rest assured I was NOT tailgating etc), anyway, next thing I know the car beeps and literally stands on its nose!
I mean it was a hugely aggressive stop, my daughter screamed, the car stopped dead and i must have been at least 5 meters away from the Fiesta and it was 80% off the road at that point.
Does this sound normal or should I be getting the garage to look at it urgently? If a car had been behind me it would, without doubt, have read ended me...
Any thoughts?
So the car autobraked to a halt, heavy enough to make your daughter scream, and stopped only a car length from the back of another vehicle...

If I were you I'd be telling people how the safety feature just stopped you having a crash.
For the life of me I cannot understand why people who cannot program a VCR are happy to crib all day long about an amazing feature (That MB seem to be the only maker who has mastered)

By braking suddenly in this situation for what would look to be no apparent reason it's increased the chance of a collision. Now it might reduce the chance elsewhere, but you have to look at the feature as a whole and ask on balance is it over all better or worse. That's all that's being asked
Just because it's doing what it's programmed to do doesn't mean that's the best thing to do in each situation.

I've had a mark 7 golf for 4 months now and mine has auto braked incorrectly twice so far..
First time happened on the first day i had the car. Slowing down towards to turn lefr at a T-junction. Only doing a couple of miles an hour and a car drove from right to left on the main road and my car stopped on the spot!
Second time i was overtaking a stopped bus with a traffic island about 15 feet in front {creating a kind of chicane) doing about 25 and as i drove through the chicane the anchors slammed on.. Pretty scary!
Get occasional warnings too when there's nothing close by..
Safe to say I'm not a big fan of the system!

It's an excellent system that works well and, in all probability, it will prevent a bump at some point.
Just get to know how it works and why it does what it does.
For instance, if it senses an obstacle and knows you're slowing (foot on break or engine breaking) it will not intervene.
It only intervenes when things seem potentially dangerous....like speeding up towards an obstacle.
By the way, turning it off and having a bump could invalidate your insurance (the system reduces the premium)!

Well slamming the brakes on as you go though a gap isn't good, is it?Just get to know how it works and why it does what it does.

It's a case of RTFM. Learn how to use the functions of your car and realise it's an assist, like any other. You as the driver remain in control.

And that's the problemJust because it 'seems potentially' doesn't mean that it is
If it then reacts in an unexpected manner, that too could be 'potentially dangerous'.
If drivers begin to rely on the system getting them out of trouble its worse

"Here's the problem: There was no system error. If there was any error, it was with the humans operating the vehicle. According to Volvo representative Johan Larsson, the video is mislabeled. Now, no one has talked to the people in the video, but Larsson says the demonstration is most likely of Volvo's pedestrian-detection and self-braking systems, not of any self-parking feature. And as Larsson also points out, this car does not appear to be one that has the pedestrian-detection feature, which is an option. If that's true—that they tried to test out the pedestrian-detection feature on a car that doesn't have it installed—then this is really just a case of dumb humans."

They cant confirm but either way it shows what I said."Here's the problem: There was no system error. If there was any error, it was with the humans operating the vehicle.

It demonstrates how humans can be led to rely on something to work when it may not
Ask if it's changed behaviour

I've never had mine activate. Most I've had is a warning beep in a situation where it was totally justified. The system and I reacted at pretty much the same time but it sounded the beep as my foot was moving to the brake anyway. First time happened on the first day i had the car.

These are drivers' aids. These are not self-driving cars.

Who says it does that? If the car senses you're on the case then it doesn't intervene. If you're the kind of driver who accelerates through a closing gap then maybe it would give you an allegedly false positive (or, possibly, it is more risk-averse than you). If you're a defensive driver working with the car rather than against it then maybe you get less intervention. Who knows?

Yes, and I get worried when this Volvo couldn't tell it was on a ferry and wasn't being stolen, yet it set the alarm off! FFS, it's obvious to a human what's going on (the captain just revved up the boat engines a bit) yet the automatic sensors can't tell something so obvious. This technology in future automated/assisted driving is not good.Even the relatively simple auto devices on my car such as start/stop and auto hold on the park brake don't always do what they are supposed to,.
