#12Sure, but try to convince people who are okay with accepting (other) deaths just to feel "in control" of a two ton vehicle.
Re: Studies find automatic braking can cut crashes over 40%
#13I wonder how many extra crashes will something like this trigger and who will pay when accidents happen because the car decided to break for no apparent reason. I've seen PCS working well at slow speeds and, arguably, they would be more helpful at higher speeds. But would you trust such system with your life at high speed on a busy motorway ?
> who will pay
The person hitting you from behind would be at fault anyway, at least where I live you are required to keep enough distance to stop even for no apparent reason, if driving in a lane and not moving to another.
If you do it whilst moving in front of another car as it could be on you as you are required to yield and leave enough space to not hinder or endanger the driving of the other vehicle. This also includes brake-checks as your obligation to yield does not stop after you have merged into another highway lane and continues for an unspecified amount of time.
So there should not be an issue there, only problem is people can and will not understand the stopping distance of a car driving 100+kph and do not leave enough space. YMMV with respect to the laws involved as it's entirely possible you could be at fault at the place you are living.

#14The title is a tiny bit misleading. Here are the stats from the article:
Automatic braking has demonstrated the ability to:
- reduce rear-end automobile crashes "in half" (technically 49%)
- reduce Rear-end crashes with injuries by 53%
- vehicles without automatic braking, but with collision warnings only cut accidents by 16% (compared to 49% with automatic braking)
- pickup trucks are less effective at preventing crashes, only preventing 43% of accidents and reducing injuries by 42% (compared to above numbers for other vehicles)
- lane departure systems reduce crashes by 8% and reduce injuries by 7%
- A consortium of 20 auto manufactures have voluntarily committed to offering automatic braking technology to 95% of their light-duty models during the 2023 model year

#16Oof, my experience with with auto-brake in a 2021 Subaru Crosstrek (anecdotal, sample size of one, all that good stuff) is much the opposite. It's too sensitive and tends to brake shockingly hard during fairly mundane maneuvers. When backing up near a wall/obstacle, the auto-brake seems to kick in when anything is closer than three or four feet away from the bumper. I use my mirrors and have an accurate impression of…
I just bought a 2023 Crosstrek and haven't really noticed it kicking on too aggressively, it does beep sometimes. The only time I get annoyed is when its in adaptive cruise control and someone is merging off the highway it will think they are slowing a lot but its clear they will be out of the way.

Results are going to vary by manufacturer. Tesla and Honda seem to have a serious problem with phantom braking.

Most other brands seem pretty good. My 2019 Subaru has zero phantom braking events so far. (Although the adaptive cruise control does get confused when driving in the slow lane on freeways and slows down when the car ahead turns onto an offramp.)
Automatic emergency braking changes nothing from a crash liability standpoint. Generally the leading vehicle has the right of way, and the following driver must leave enough space to avoid a crash even if the leading vehicle brakes inappropriately.

The rules for accident liability aren't as rigid and naive as you are implying.
The rear ender having to pay is just the base case that is used in the absence of other facts.
If you drive "in an asinine manner" (the definition of asinine is subject to discretion and negotiation between the relevant insurance companies) and manage to make the front of someone else's care meet the rear of yours in the process AND there are witnesses, dashcam footage or other evidince you will almost certainly wind up having to pay up.
Everybody knows that traffic doesn't follow the rules. Pretending like it does is a convenient legal fiction we use in order to make rule making easier.
There is intentionally tons of redundancy baked into the rules to cover for all the edge cases where people routinely don't follow the rules. Hence why other people's obligation to not crash into stuff isn't a blank check to do whatever. In cases where two people are breaking the rules usually whoever's breaking them in the more typical and predicable manner is the one given a pass (e.g. someone speeding "a normal amount" will likely not be found at fault if you roll a stop and get t-boned).

#19I don't have an automatic brake in my car, but a sensor that warns me when I'm about to crash into something. There has so far been a single incident where this was actually helpful. In >95% of the cases, it's false positives.
I can only imagine what driving would be like if the car did indeed autonomously brake in those situations.

#20Someone recently opined that the boffins should have started with collision avoidance. Then build up to FSD.
Facepalm slap. Seems so obvious once said out loud.
That'd be like a Rodney Brooks inspired actionist strategy, right? Our vehicles as boids, with implicit coordinated action, like flocking, herding, pacing, station keeping, etc.
Maybe a bottom-up emergent behavior strategy has potential. Or a hybrid strategy.
When it comes to AI, FDS, etc. I obviously know nothing about nothing, so please chime in.
