I've had the collision alert give false alarms from approaching another car too quickly, but I have never had it alert or brake for a pedestrian ahead. I think if drivers are getting annoyed by false pedestrian collision detection alerts, they are approaching pedestrians far too closely/quickly. It think would take quite a bit of psychosis to actually drive in a way that you were “relying” on AEB. You mean like approaching an intersection with phone in hand, and eyes on the phone? I see it every day.

> approaching an intersection with phone in hand, and eyes on the phone I think the point GP was making is that those people who are prone to do so will do that without AEB just as much as with. I'm a full driving automation sceptic who believes that even automatic transmission makes people more dangerous drivers, but even I can follow the argument. Unlike many other elements of car automation, AEB isn't meant to move a task from doing it yourself to supervising the computer, it's the reverse of that. And even if AEB worked 100% reliable every time, drivers would still try to keep AEB engagements at zero because the sudden maximum braking is so much less comfortable than regular braking.

  Re your first paragraph, I don't agree - people will consider it safe to drive and not pay attention 'because the car will stop me hitting anything'. During rush hour in my UK city I reckon on about 1-in-50 drivers I see using mobile devices in hand whilst driving. Most appear to be lone female car drivers, most dangerous are male lorry/van drivers (who presumably are using delivery/routing apps).

  Yes, AEB is specifically designed to avoid the problems we saw with earlier interventions like ABS where users who don't understand the technology may mistake its safety interventions for their own skill and so trick themselves into driving worse than before. AEB deliberately chooses maximum braking to a full stop because that does NOT feel like skill, it correctly feels like you nearly died just there. The experience is intended to be "Oh shit" not "See, I was never going to hit that, it's fine".

> I think if drivers are getting annoyed by false pedestrian collision detection alerts, they are approaching pedestrians far too closely/quickly. What? No, it means they are approach bridges at perfectly normal speeds. Or glare in the Sunrise/sunset. Or random things blowing across the road that aren't actually pedestrians. False positives are a real problem.
