I have a modern car (2019) and the auto braking, collision and lane drift alert is a nuisance. False positives are common and there is no way to disable most of it. Some of it can be turned off but as soon as the car is restarted it resets to the default. I've even had the car emergency brake and come to a complete stop in the middle of the road due to a phantom collision. As soon as I pay it off I am going to sell i…
Weird that you cannot disable the collision warning and lane keeping. What Make/model is it?
Looking at the comments here I need to double check if I'm on some gearhead forum where automatic transmission is considered appropriate exclusively for teenagers and geriatric patients. Anyway, I'll add my anecdote when my Toyota surprised me with a panic brake in a blind corner which probably saved my life by not ending up under a stopped bus. But the kicker is that my insurer gave me quite a steep discount when I…
Insurance companies are run by people that are good at statistics, and there is a fair chance that statistically this works out well but that does not mean anything for any particular individual. Chances are that EAB will cause some accidents and prevents a whole lot more, and that's enough for the insurers.
This feature once saved me from what would have otherwise been a very nasty crash, many years ago. I was driving too fast in a borrowed car over a small hill and hadn't realized that traffic had stopped just out of my sight until too late. I heard a beep and saw flashing on my dash and I started braking but a moment later the emergency braking system kicked in, braking much harder than I would have been able to. The…
Seatbelt tensioners are life savers. They're a little explosive charge under the chair near the seatbelt attachment point that yanks hard on the belt to squeeze you against the chair while the car comes to a stop. They're super powerful and you don't want to mess with them unless you know exactly what you're doing (see also: airbags).
so if someone merges over into your lane where you are it doesn't activate? I must not understand the point of this feature then.
On my Honda if a car merges in front of me and is accelerating, it maintains its speed presumably on the assumption that the separation will continue to increase. If a car merges in front and is slower than me, i.e. separation is decreasing, it will brake in an attempt to maintain the set following distance. In practice it does leave a bit more following distance than most human drivers, but your worry of constantly…
Also, at least on mine, it doesn't attempt to implement the full follow distance right away. Mine can tell a vehicle is accelerating away from me and won't slow down to fit the spacing on the expectation that the spacing will soon be achieved by the other vehicle. If the vehicle in front of me is going slower than my set speed and not accelerating, then it slowly will lag back to get the set follow distance. You do have to worry about aggressive cars that cut you off in heavy traffic as the vehicle will just let them and lag back, but I can at least adjust the follow distance to partially mitigate this situation.

Usually you can disable it but on a per-ride basis and it takes a lot of menu scrolling and tapping to do it again. It defaults to 'on' when you start the car, and there is no physical switch to disable it permanently.

Yes everybody here seems to be ignoring that car accidents are the leading cause of deaths for children and young adults… car safety is not a solved problem!
Would you care to elaborate on what went wrong? The other comments here make ‘automatic emergency braking’ sound like a really good idea, and it’s hard for me to imagine that this particular feature would be so problematic. If you’re talking about other automatic steering features, that’s very different, and your comment makes more sense to me.
Not the person you were responding to, but here's an anecdatum: One time I was driving behind someone under otherwise normal conditions, and they turned right into a parking lot. As they turned right, they obviously began exiting the road. The screen on my car screamed "BRAKE!" and then the braking system activated. They were about 60% of the way into the parking lot, and continuing to exit. I was at a normal followi…
I've had this exact situation happen on numerous occasions. It's always people turning into a parking lot ahead of me, in a situation where they will absolutely be out of the way long before I reach them, but also I'm actively shifting to the side to go clearly around them anyway. In none of the situations was there any chance of an accident even if the turning car stopped suddenly instead of completing its turn. And this has happened to me on multiple different vehicles.
Each time it happens my immediate reaction is "what the hell is wrong with my car" before I see the "BRAKE" on the dash or heads up display and realize this happened yet again. I'm surprised I haven't been rear ended on account of it yet.

I fully understand that frustration, but I would point out that continuing through the departure zone like that at full speed is prone to accidents with another car entering the road in that blind spot and you should adjust accordingly. Additionally, following the car in front of you so close that you hit them if they brake suddenly is inherently dangerous and a bad habit as well. Interestingly enough, a universal AEB requirement on all vehicles would help in that scenario.

Every possible change to a car’s safety system will cause some deaths and save others… look at airbags.
The aggregate stats are the most important things to look at, especially for something like AEB which has the ability to save pedestrians, which as of late are getting mowed down more and more frequently.
This almost got me into a serious accident, twice. Definitely would not recommend and I switched cars because of it. The last thing I need is buggy software with the capability of instantly changing the trajectory of my vehicle (slippery surfaces, cornering). A brand car as well (MB) so really, really disappointed, what should have been a safety feature actually was the opposite. Dealer said everything was fine so th…
I wrote up a long comment that got scrapped by my focus filter but I feel the need to voice strong agreement here. I have a recent Mazda which in almost all ways is my perfect car except for the newfangled safety features all new cars seem to have. Lane correction and emergency braking, even set to the lowest sensitivity levels, are bad to outright dangerous in city (and some country) driving. In NYC it's common to have multiple road lines crossing during construction which by default has lead my car to try steering into cyclists or barriers. It can't read the lane because the lane is not properly marked but that's typical. So I disabled it. Emergency braking is a bit harder for me to understand when it kicks in but I've done whatever I can to keep it off. Twice it caused a hard brake in the middle of traffic with my newborn in the back and almost got me rear-ended. Another time it detected another car ahead of me but technically in the next lane and warned that it was about to hard brake in the rain on the Williamsburg Bridge inner roadway which is... tight to say the least. If there's a future where these features are rigorously tested for worst case scenarios in different driving environments and somehow universally implemented across manufacturers... maybe.
