Keeping it on at all times sounds like a terrible idea for cars used in the US, because it's a developing nation with extremely poor road quality. In developed nations, it's probably OK because you can count on the road markings being good almost everywhere, but not in the US.
But yeah, you need to make sure there is a physical button on the steering wheel or somehere on the dashboard to easily enable/disable it. Otherwise it can be annoying.
For AEB, the same system is used in the adaptive cruise control and it's been near perfect. One funny thing was that it just alarmed and fully died in outback Victoria - apparently it is coded to do this as a fail-safe if it hasn't detected a car for a long time due to the system potentially not working. The service centre employee said Hyundai are working on a patch to extend the timeout since it's a little low for country Australian roads (approximately an hour at the moment I think).
Been driving an Ioniq 5 2023 for a couple months now with no phantom/emergency braking issues. I'm not in love with the performance of the lane keep without being on an HDA2 marked highway. I have to fight it just enough for it to not be useful on certain well marked backroads.
Considering tossing in a Comma 3 to give no-hands driver assist a shot.
“In 2020, NHTSA announced civil penalties for the companies—totaling $210 million—for not recalling vehicles in a timely manner. In 2021, a whistleblower who provided NHTSA with information that led to those penalties was awarded $24 million, the agency’s first-ever whistleblower award.”

They have great styling that’s comparable to German cars. I wish the US automakers could take some hints. From what I’ve heard the Genesis lineup is very luxurious.
In cases where it’s not possible to disable the feature we better constantly record the car from all angles to have it as a proof against the manufacturer in case something goes bad. Near accidents caused by buggy software should not get a free pass, but require the manufactuter to fully reimburse you or pay you some serious fine.
But in the south? Not a single one of the original poster’s complaints are valid here with the exception of cars who cut you off and then speed away (no need to slam on the brakes, cruise control). Personally, the early brake warning has saved someone else’s property at lease twice.
Right, if I had to condense my issues into something more constructive it is just that: if regulators want to pursue a mandate for these systems, they should also work on establishing testing criteria and specifications that cover the many different conditions drivers face and reduces variation between manufacturers as possible. Not an easy task.
To give a quick example: another commenter in this thread states that lane assist only kicks in at 35mph. That is true in some models but not all which could lead to some nice surprises. Further, the speed limit in NYC is 25mph so it's not unusual if the road surface is decent to be cruising closer to 30. Unless there's a threshold for activation, you might be walking a fine line between "safety on"/"safety off" and any resulting corrections it might make.
If I accelerate into traffic and get close to a car while accelerating, it will start flashing a warning light and if I still don't stop accelerating or braking, it will intervene, but if the other car accelerates it doesn't do anything. So the radar setup is quite well done and it gives very few false positives.
The lane assist system is a bit bad though because once it identifies the lane markings it does not take into account potential hazards that want me to change a lane or exit it for a few seconds to avoid road hazard lights or something similar.
The point I am trying to make is that there should be a high standard to what drives the AEB and it should not rely on cameras, which seems to be what automakers want to implement driving assisted features to save on more advanced tech. And somehow I don't think they're gonna pony up for high-speed cameras that can replace a radar at accuracy.
Maybe the intention is good, but most likely the implementation will suck.
Thankfully it is possible to have the system set to beep only as slamming on the brakes while merging is an experience everyone wants to avoid.
Also, it sometimes panics when coming to a stop on an incline with a car ahead. I guess it is unable to account for the fact that the car will stop by itself just because the road is going uphill?
Recently upgraded to a Chinese ute. I've about the first 1000km driven now, and whilst it's occasionally made some mistakes, if my hands are on the wheel it's easy enough to just stay the course and it let's me do as I wish. I can also turn all the setting to off at the touch of a button and make that the default too. I quite enjoy having these features because they have been implemented well.
- when it works it works so well the car basically drives itself esp. when you throw cruise control into the mix (this includes auto coasting + breaking)
- when it doesn't it's bouncing across the lane + applies too much resistance when attempting e.g overtaking
I did not have any issue with emergency braking (never triggered, any situation where it would have triggered got handled by the driver first), but I did have a few (light) phantom braking events in cruise control.
Not related to lane assist control (uses a separate mechanism) but I did have issues with blind spot alert, it was randomly alerting regularly when no car was present. Mazda identified the cause as winter tyres throwing the sensors off. A software update is supposed to fix that but we disabled the feature so it'll be done on the next scheduled maintenance.
It doesn't turn off when you indicate to change lanes? It does on the Hyundai.
Makes me laugh every time. I mean, at that point, why bother with the signal at all?
There are still scenarios where it can be an issue, for example when you need to "peek" through the lane to see if an overtake is possible safely. In this case it requires driver judgement on when to activate the turn signal. You may activate early or when committed, I don't think either is necessarily wrong.
I don't know the other commenter's scenario but don't doubt what they described. To pull another example out of my hat: bendy mountain roads (e.g. western Connecticut, minimal elevation changes), car ahead is moving slowly due to lack of power, heavy load, etc. Assume driving conditions and road lines are clear, no camera or sensor obstructions. The system is automatically active while following the bend and will attempt to keep on course. As you approach a rather wide curve (lanes are also widened, with extra shoulder) it is an opportunity to ride closer to the centerline in order to see past the vehicle and overtake. If you do that without putting on your blinker first, the system will attempt to correct while you're in the turn. Depending on how you react this can be jarring as the wheel is vibrating and you have to decide whether to commit to let the system correct, correct the correction, or commit to the overtake.
I chalk this up more to my own lack of familiarity with the system early on and not a defect per se. The wheel vibration is a very odd sensation to me on turns likely because on older cars I'd start to worry about tires or mechanical issues.
I've been making productive use of the "textarea cache" extension lately. Sites and browsers lose text a lot more often than they should.
I’m more interested in this
They'd need to be implemented and then turned off for 15 years until 99% of the old cars are off the road and then flipped on simultaneously for every car.
If a car suddenly breaks then the car behind it better be able to suddenly break too.
