And how many more cars are going to be produced and bought because of "planned obsolescence" when electronic systems in modern cars start to give up (eg. electric cars and their engines should be able to last for a really long time)? Are they going to keep getting security updates for 20, 30 years? Or will we start seeing people doing something to fool their sensors so they crash?
While I like all the technology, it's short-sighted to think that the alternative is desired simply because people don't care about potentially hurting someone with their cars. Like everything else in life, this issue is multifaceted too.
Everyone thinks they're a great driver.
Automatic braking will prevent you from rear-ending the car in front, yes. Although an attentive driver should also be doing that.
Society doesn't allow people to say that they're good enough to opt out of safety mechanisms designed to protect us all.
This is why 'I don't wear a seat-belt I can brace myself' also doesn't cut it.
A seatbelt is a safety mechanism.
Driving assist functionalities encourage unsafe behaviors of drivers more than safety. Why should I pay attention to the road if my car will automatically brake for me? Well, until the one time it doesn't and someone dies.
For example ABS increased crash rates for a good while when it was new, contrary to all expectations.
From this NHTSA report: https://crashstats.nhtsa.dot.gov/Api/Public/ViewPublication/...
"Analyses of data from the early 1990s showed significant increases in fatal run-off-road crashes with ABS, on the order of 28 percent. The increase was baffling, given the success of ABS on the test track. However, at that time, many drivers did not yet know how to use ABS correctly."
I observed this effect first hand, because from the late 90s to the late 00s I was frequently a car control clinic instructor. One of the exercises of these clinics was to teach panic braking. In the earlier years most people showed up with non-ABS cars so this was a great exercise in teaching proper braking control.
As ABS cars became more and more prevalent we (the instructors and the school) thought that this exercise can go away since there is no skill to learn braking if you have ABS, just mash the pedal.
Alas, no! It is difficult to believe, but approximately nobody that came to these car control clinics with an ABS car was actually able to initially brake hard enough to even activate the ABS. Sometimes it took many many runs through the braking exercise to finally get it: just press hard on the brake pedal.
Was literally an argument people made against seat belts.
(I'm old enough that seatbelts weren't a thing when I was a kid, so I remember well the arguments when they became common and later required.)

Meanwhile, any driver worth his salt should be checking cross traffic when nearing any intersection. I've avoided several accidents by examining potential cross traffic at intersections.
Accident avoidance should be drivers ed 101, but for some reason, especially in these conversations, no one seems to know how to look for and avoid potential accidents.
Although, I'm dubious there would be enough time in that scenario to help much. The typical case is someone running a red light and intersecting a car from the other direction, both going full speed. By the time the tbonee car enters the field of the tboner car front sensors they are very close and less than a second from impact. So it'd reduce speed a bit which is good, but won't prevent the hit.
An attentive driver on the other hand, can see far wider than the sensors and has more opportunity to avoid the incident entirely. If paying attention, of course.
There are arguments to be made both ways, but there definitely isn't a clear solution.
Automated system would have advantage there only where it can better "see" things (eg. LIDAR in pitch dark conditions, or maybe positioned at the roof of a vehicle and seeing over other vehicles that a driver can't).
My point was that for attentive drivers, "safety features" are more a nuisance than help in their own car (the worst you can do is have frustrated drivers behind the wheel). If that results in drivers disabling them, we are not better off at all: technology does not get developed and never matures enough not to be a nuisance. I keep them enabled, but I can understand that not everybody wants to go through these rough edges.
It's by no means perfect (and the city beta is kind of a mess), but the highway safety bits are very functional and useful.
Reaction time in all the car-braking studies is usually measured at 0.2-1s.
That's indeed the time a computer can use to their advantage, and maybe Teslas do, but many in-car systems today are not that fast, and esp not the one in my Volvo. All the things it does it seems to do them slightly later than I'd like to for a seamless, defensive drive.
It's all a matter of cost of per-unit hardware (processing power), development time and state of the art.
We'll get there, but we are not there today.
The automatic braking seems to be the most dangerous one so far, at least on Teslas. Countless incidents of the car slamming on the brakes at highway speeds for no reason whatsover. Brake checking people at highway speeds is highly dangerous road rager action, now cars are automating behaving like this.
Things like auto lane control seem more benign, but they do suffer the same dangers as the so-called autopilots, in that they lull the driver into paying less attention which will always be more dangerous until true AI level 5 self-driving exists.
I don't trust the features to work well enough to rely on them. And I think other people having them is dangerous.
Meanwhile, they all can be toggled off, so I still won't be using the feature. It's just another point of failure shortening the lifespan of a five-figure environmentally costly purchase.
