That does seem really dangerous, in terms of people who aren’t expecting a he cars they’re to stop. Or then our expecting their cars to stop and their cars don’t stop. And how bad we know Teslas are at stopping.
On the other hand, if it is implemented, people will be driving super carefully.
adding this kind of a feature seems like it’ll make cars more difficult to drive, and people are already so bad at driving.
This is an emergency brake, ie it will wait until the last possible moment and brake full on. If the driver wasn’t expecting it to stop, then they weren’t paying enough attention to the road in front of them
What about malfunction or misidentifications?
Errors in any machine are common, and errors in automatic driving systems are ubiquitous and constant.
I’m no mechanic, but I’d guess there’s multiple/redundant sensors so the case where one fails is handled. It is a concern but I’ve never heard of that kind of incident happening in the years they’ve been around

And that hot coffee will be all over the place. Tough.
@FatLegTed @DrCake When I went to driver’s ed, the instructors repeatedly reminded us that we had to be prepared to stop at any time because the driver in front of us could brake for a squirrel or encounter debris in the road or stop for any reason. Most drivers don’t seem to understand the basic physics that stopping distance increases with speed. A key feature of driver assistance systems should be speed-based tailgating prevention.
These rules are convoluted and near impossible to apply. Specific braking speeds for some objects compared to others? That requires reliable computer vision, which hasn’t been demonstrated anywhere yet.
And those speeds? 92mph is 148kph! Why the fuck are cars even permitted to be capable of that when no road in the country allows it? And why would you want to introduce unpredictable braking scenarios at such speeds?
What is feasible is a speed limiter based on the posted limit, but that’d be too practical.

I have recently got a car that tells me the currently posted limit and it is frequently wrong. It misses sign posts and sometimes thinks that a signpost for a side road applies to you.
It also has a speed limiter and a button to set the limit to the detected speed which I use a lot but I wouldn’t want it to do it itself.
Thing is like none of our roads are properly tested for the posted speed limits. Interstates can often go up to a 75 limit and regular traffic will go at 85 (because cops dont care til more than 10 over and that difference adds up on long trips) with some people going 90+.
If the car is now expected to do the braking for me, does that mean I can floor it everywhere, knowing the car is supposed to brake automatically when detecting collisions etc. If it fails, who is liable? Driver, or faulty software?
“The car has AEB and it failed to detect the person in the road. The car and braking system failed so I am entirely not liable. Go sue ford instead”
Cars have had automatic braking systems like this for ages. The driver is always going to be the one responsible (short of some actual fault in the car)
Have had them for ages
Ive seen Volvo lorries with that, nothing else.
What cars are you seeing that have what the article is discussing, already implemented?
I don’t know if they meet all the requirements of this law, but I’ve seen Subarus, BMWs, and a Porsche that all had some form of automatic braking.
I think the Porsche was the oldest, around 2015-2016. It could keep even keep pace with the car in front of you
The one rule I would dream of seeing is soft speed throttling to ensure that cars and trucks stay a safe 3 second distance or more apart from each other. That should be relatively easy to do with basic distance sensing and calculations.
Duno about newer cars, but in a 2017 model bmw it tends to brake for parked cars quite often when using radar cruise control…
The Cupra Born I drove the other day (don’t own a car and rely on carsharing and rentals for my business) while doing deliveries for a catering event did this. It was really annoying driving in narrow streets with it braking for parked cars.
My 2017 Volvo just warns me if there’s a parked car in a curve, never had it brake automatically for parked cars no matter the scenario, so I guess it’s just that BMW’s system wasn’t quite there yet at the time…
Ah true, yeah I test drove a polestar and a Hyundai ioniq 5 before deciding to go with the bmw and they both worked a lot better, but were also way more expensive since they were new and the bmw was second hand 😅
Unfortunately there weren’t any second hand phev volvos available in my area at the time.
Was going to ask the same question - cruise control is for open roads like motorways. Not around town. No wonder they had issues with it.
Maybe you don’t. But ancestor post is suggesting to make it mandatory to avoid tail gating and then it had better work properly.
Fucking tailgaters. No idea why so few people seem to be aware of how dangerous and stupid it is to tailgate.
obligatory reference
I haven’t read up on the new law but the EU already mandates that all new vehicles are required to have “advanced emergency braking”.
I wonder how different that actually is from the US law, or are the car manufactures making a fuss over something they are already doing somewhere else.
