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…

Name the car brand and model. Not all implementations are so bad, so it’s important to raise awareness of the bad ones.

Seconded, better yet a public registry of locations and situations where these systems go off so that manufacturers can include these in their tests.

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.

Wasn't AIG an insurance company? They don't seem to be good at math, much less statistics.

Exceptions, rules and all that.

Not the poster Vw golf r 2016 the sensor was low to the ground and it would randomly brake for stuff it thought was a threat like a cardboard box. Subaru crosstrek 2018 - would brake for no reason, cars turning up ahead of me, etc. VW atlas 2019 - brake for no reason would also scream at me and show a red symbol on the hud when nothing was in the road in front of me. Subaru impreza 2023 - brakes for turning vehicles…

Why not get a car without that stuff?

I got what was available at the time. The golf r is low production car finding one to buy was hard enough.

The crosstrek the only orange one available had eyesight.

The atlas was used so there was only 1 option locally

The impreza its standard on anything over base, and the base was missing other things i wanted.

Ok, that makes sense. I just bought a 1997 car and had it rebuilt, about 30% of the price of a new one and none of the crap, roughly just as safe as the current ones and much less likely to be stolen. Not the most economical decision because of course it is still a 1997 car but it will hold its value well enough that I'm not worried about it and I'm not really planning on selling it anyway. But if I ever do crash it then I'll probably lose a bunch of money because the present day value is less than what I put into it. Otoh just the write-off on a new one would have been roughly the total invested.

It's very frustrating how tech can be mis-applied. But I also see the regulators point of applied statistics and that even if these systems cause the occasional crash they prevent a much larger number from ever happening.

My Kia likes to trigger the ~~AEB~~ Collision Avoidance warning when people are turning off the road in front of me. It's really only triggered when it _thinks_ a vehicle is in my path, but it's really exiting the path and just still in the periphery. I get about as many false positive type events with the lane keeping feature. I've learned, the hard way, that not all lane markings are to spec. The worst are when you…

Yeah the lane keeping for sure is bad because even if perfect there is a lot of real word situations where one needs to deviate from the center of the lane. So unless the vehicle is fully self driving to the level of an alert good driver, it’s going to mess up. And lane keeping is definitely not claiming to be that. The lane departure warning beep is fine even although its 90% false alerts for me due to non-lane line…

I find the lane keeping and departure warnings lessen the cognitive load on driving. I find I'm able to expand my focus when driving a bit more and improve my overall situational awareness. Overall, I'd say it's a great thing. That and 360 degree birds-eye view cameras when parking are safety features that all cars should have.

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).

Interesting! My recollection was that it was a non-explosive tensioner, but maybe I'm wrong. Thinking about explosive tensioners reminds me of an EOD tool I recently learned about – the rocket wrench. https://www.youtube.com/watch?v=11qa5LFB6zI [1:36]

Weird that you cannot disable the collision warning and lane keeping. What Make/model is it?

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.

I imagine there is no permanent disable because it is a "safety" feature. But at least on my Subaru disabling it is a physical button. No scrolling and tapping required. On the other hand, it also works well enough that I haven't felt a need to disable it.
