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'm so glad this is the top comment. Ghost braking is a far worse problem.

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…

It's not exclusively a "gearhead" opinion to not want a system in your car that can violently take control away from you unexpectedly Statistics are meaningless to the individual. Sure, emergency braking might be safer across the board, but that means little compared to an individual who already drives safely without it.

I have two vehicles with this system and they have never “violently taken control”. In most situations, the system gives an audible alert while pretension the brakes. If you react within the alert window you retain full control with the benefit of firm brakes (y’all ever remember getting soft brakes?).

I don’t even want to know what situations I’d need to be in for my vehicle to actually emergency brake, but I don’t want to find out. It seems like I’m already going to be hitting something anyways so any speed it can bleed off is better.

I confess that I find a dark humor in how many self professed "great drivers" find these features a nuisance. All the while so many people are completely unaware that they have these, as they have never activated. Hard for me to square those pegs in a favorable way. Which, yes, being a great driver means you may be pushing close to limits while still be completely under control a lot. I just don't have a strong prior…

I am reminded of the quote, often attributed to astronaut Frank Borman: “Superior pilots use their superior judgement to avoid situations that require use of their superior skills”

There's a similar one among sailors: "The mark of a great shiphandler is never getting into situations that require great shiphandling."

Anyone operating a machine in a way that doesn't leave much margin is, in fact, not skilled at operating that machine.

> > Statistics are meaningless to the individual. > This is just blatantly untrue. This statement is blatently untrue. If a "driver gets in an accident every X miles/km" does that mean if you drive more than X miles, you're "overdue?" No, that's a statistical fallacy. Aggregate statistics are only meaningful if you're within a standard deviation of the mean. If you are a safe driver, it's likely to be meaningless. If…

> If you are a safe driver, it's likely to be meaningless. No. You are sharing the road with others, of variable skill, and things like deer and pedestrians who can dart into traffic. I’ve been crashed into from behind while stopped in traffic; no fuckup on my end, but still would have likely benefited from automated emergency braking. Your car insurance also reflects others’ accident rates. You shoulder some of the…

Ok, I see where you're going with this, let's mandate for bad drivers; now everyone is happy.

There needs to be a tiered license then - if you pass the more rigorous exam you can drive cars without the extra "safety" features. Making AEB mandatory would increase the survival rate of poor drivers and punish people who actually pay attention on the road.

> and punish people who actually pay attention on the road. It can benefit people who have reaction times slower than silicon.

It can also cause accidents, and some people go their whole lives without getting in an accident.

The B in AEB stands for “braking”, not “steering”, so I don’t understand what system you’re referring to that would steer into cyclist traffic

Lane keeping assistance, from the context.

Lane-keeping should only be active with cruise control active. You shouldn't be using it in city traffic, ever.

I see a lot of comments in there in the lines of "it almost caused an accident!". Yeah, my AEB has misfired too, often when coming around a curve and it thinks I'm about to have a head on collision with the oncoming traffic even though we are both turning. Or when making u-turns with a car in front of me. But it's never caused me to get hit. And more importantly, if the other cars around me also had AEB, then they to…

My AEB is overridden by an increase in throttle; even a small one.

If (rarely) it misfires, it’s only pretensioning the brakes initially. That’s just getting the pedal firm and pads against the rotors, no braking force. A small bit of throttle, not even enough to speed up, is enough to tell it to cool it. No actual braking occurs.

Anyone who’s losing control of their vehicle over that is already driving too close to the vehicle’s limits.

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.

Which is funny considering the explanation that was presented to me about why is it legal in the US to ride a motorcycle without a crash helmet. The explanation is: in case of an accident, the motorcycle driver has a lower chance to survive without the helmet. From the insurer’s perspective paying out a one time death insurance might be cheaper than paying someone money every month for the rest of their life. No idea…

> why is it legal in the US to ride a motorcycle without a crash helmet.

This depends on the state:

https://www.cdc.gov/transportationsafety/calculator/factshee...

> As of 2021, 18 states and the District of Columbia had universal motorcycle helmet laws, 29 states had laws requiring helmets for certain riders, and three states did not have any motorcycle helmet laws.

I can't count the number of flowers AEB has prevented me from murdering. But at least in my equiped vehicle, the nuisance activations haven't been dangerous, and most of the events in traffic have been reasonable, if overly conservative. During parking, less so, but at least predictable. Having AEB without being aware of it is probably not ideal. If it activates improperly and you didn't know it was there, that's twi…

Sadly, most anything is disorienting in crash situations. I recall how disoriented my mother was when a car came from the side and almost hit us. She tried braking and swerving, but that just caused a hydroplane and when the wheels got traction again, jerked us to the side. She was convinced the other car hit us. I was, too, all told. Until I saw that there was no impact on the side of our car. Which is to say, you a…

With all due respect, it sounds like your mother oversteered more than anything. AEB has little to do with that.
