my 2020 civic seems to do okay but I get those issues only on occasion. Newer tech would be more stable I think. Only been driving it ~3 months.

When we looked for a car a couple of years ago (and, more recently, when I've driven rentals), station-keeping was certainly no better (and in at least a couple of instances, definitely worse), and as noted by everyone else in this thread, the whole system is so darn annoying. Of the beeps and warnings which are not false-positives, most draw my attention to things I've already seen, so they become either distracting or ignored, which is a net safety degradation.

I think 2015 driver-assist systems (or Honda's, at least) worked better.

Moral of the story, the features are far from perfect, and I would prefer the number of times the car moves the wheel for me to be 0.

Not in a Tesla, but I've rented 3 cars as of late where driving through construction zones with shifting lanes caused the wheel to jerk constantly as it thought I was leaving a lane.

I'm aware enough to catch it and so on, but man it does not come across as a safe feature in that regard. I would be curious to see what amount of testing is done for this scenario, since construction is a common enough thing to encounter.

The two current cars in the family both have exactly the same bugs with their "collission warning" (and some unique ones). They both will consistently issue the RED-FLASH!+BEEP!!+BEEP!!+BRAKE (sometimes), when driving around a turn with a car or especially truck parked on the outside road shoulder. The car cannot figure out that I'm not going straight into the "obstacle", and so warns me. Too late for me to actually do anything about it if I were to actually be heading straight into the parked obstacle, but it goes right ahead. The only possible benefit is if it is also silently pre-tensioning the belts & priming the airbags, but it could do that without the histrionics.

Both cars also far too often will alert on mere cracks or patches in the road ahead, with no obstacles.

There are other times they mis-alert in their own ways or randomly, and it isn't often enough to dump the cars, but it is definitely bad. The warnings are also timed so as to be absolutely useless were it an actual emergency, and I say that as a qualified & championship-winning road-racing driver who has at least better than average situational awareness & reaction times. I can say absolutely that if this "warning system" were to be my first alert to an emergency, there is no way I could take effective action in time.

So I have no idea who are the clueless wankers designing and implementing it; it is evidently for only their own self-satisfaction to justify their existence. Sad.

I agree most of them are surprisingly good -- the forward collision warning system on my Golf R only made a few mistakes in the 3 years I owned it, and they were all "understandable" mistakes where the tech clearly didn't understand why it was 'wrong' -- eg, I refused to lift throttle because I knew the car in front of me was about to accelerate due to the light which had just turned green, or I elected not to brake because the car cutting in front of me was swooping across two lanes so it wasn't worth panicking about.

The system on my Model 3 is GREAT, but only when set to "late" ; my aunt's car was constantly hassling her until I found the setting and moved it from normal to late.

But there are other such annoying automated systems -- my Golf had a REAR collision warning which would fully engage the brakes if you were reversing down your driveway while a car was driving down the street behind you. I suppose it wanted me to wait until the road had NO traffic before daring to reverse on my own private property.

Also, some cars try to overthink things for you. I've driven vehicles where if you drive in a spirited manner, lifting off the throttle abruptly and engaging the brakes quickly but not aggressively, it decides you MUST want to perform a panic stop and doubles the brake pressure. I think most of us can agree that we want our machines to perform in a reliable and consistent manner and not have basic controls second guess us?

This is the primary reason for emergency brake assist kicking in for me in my car, Skoda Superb (VW group so similar software). It's only ever happened on the Autobahn where there can be higher speed differentials. It's a bit annoying when it does, but it's all controllable.

Other than that, I find my car's safety stuff pretty good. Lane assist isn't intrusive, traction control is functional (car is 4WD 280hp), warning tones are relevant and customizable, etc.

The one example of me driving aggressively had nothing to do with forward collision warning, and was actually about brake boost systems that choose to brake more aggressively FOR you when you might not want it to, and it has nothing to do with any cars anywhere near you.

it's less disruptive to traffic in general, including your own vehicle.

I once had a rental engage full brakes when reversing out of a parking spot because a shadow fell across the rear camera. Car stopped so violently I thought I hit something. Nearly shat my pants.

I actually leave this system on though as it general doesn't have many false positives. I turned off the suicidal lane keep feature almost immediately as that was trying for force me into potholes and debris on the road in its zeal to maintain the lane position. Completely insane.

The most irritating thing is that if there is dirt on the car it disables itself. Which means it doesn't work during half the winter due to road salt. The same goes for the backup camera, I feel like it needs a mini wiper!

Nonsense. I live near a fenced parking lot next to a highway. When I gently back out of a spot at 2km/h, approaching the fence, my car slams on the brakes. Because a car is driving down the highway. Not toward me. Not on the shoulder. But almost two lanewidths away, and behind a fence.

No. I can't "slow down and leave adequate braking distance" to ameliorate this. I try to avoid that side of the lot, but sometimes I can't. I need to wait for a lull in traffic. Because the automatic system on my almost brand-new car is hot garbage.

In a traditional European city with lots of tight, one-way streets, illegal side-walk parking on them, or short time window available to merge into congested traffic, I'm seeing my 2020 Volvo constantly complain thinking it's about to have a collision with a parked car as you drive around potholes (and point a car slightly to parked car's tail), or abruptly breaking as you slowly reverse back into street from a parking spot because of incoming traffic (eg. other driver behind in the street slowing down to let you merge but not fully stopping, a pedestrian anywhere in the ~8m radius regardless of the direction they are going, or "cross-traffic" coming from the other direction not crossing your lane). I get automated braking happen at least few times a month (I started ignoring collision warnings, so I have no idea how common they are), and I don't even drive that much (35kkm over 3+ years).

OTOH, I did see it react and break properly at exactly the same time as I pressed on the brake pedal when another car unexpectedly cut in front of my car 2 times over the last 3 years: so I appreciate the system being there and I hope it will react even if I am not attentive enough, and I am not looking to turn it off.

But is it annoying and overall stupid? Yes. Could other systems be much smarter than the one in my car? Oh, yes, and I hope they are!
