All road vehicles should have autonomous emergency braking

And the car behind it?

Either way, if it's formula one he's annoyed about, that was mentioned in one post and one video, so even less exposure, until he brought it back up again (twice).

Top tip: if you think something is getting too much air time, stop talking about it yourself

Yep sure.

I made a decision it was safe to do some kind of braking as it wasn't a child and I'd rather not hose down my tyres and that I was ok as there was nothing behind. At the same time I figured if I hit it, I hit it. It wasn't a child.
Because sudden braking I'd only consider necessary for a child. If the autonomous braking was cutting in for paper bags, cats, squirrels and whatever else then that's likely to lead to accidents. I don't expect a car in front of me to suddenly brake or my own car to do so. Even if I am driving perfectly there will be others who won't be. What about them?
It isn't. Note your word "should." Not everything is like that in the real world. You could be the best driver in the world. Others aren't. Read all that again and assume we are talking about a bad driver.

Exactly. Give it a hundred years and we are all automated air cars this won't be a problem. Mix some cars driving autonomously with other cars being driven manually and with bad drivers you will have problems. Which is what this is about.

Good point well made.

I’m guilty of inference @Crafty I do apologise for thinking you are a good driver. So you are as sh*t as the rest of us, join the club, a big thumbs up for being so honest.

Exactly what? People do emergency, unexpected braking now already.  People already go into the back of people by not paying attention, not even under emergency situations.  It's probably happened half a dozen times while you've been reading this post.  People also drive into people by not paying attention, as well as unavoidably.

Your edge case is a car following too closely to another and an expendable object coming out the front driver might not mind destroying and the front driver choosing not to stop and the rear driver not reacting in time.  I wouldn't feel comfortable trading that fender bender for the many real serious collisions that could be avoided with technology like this.

The crisp packet incident is not good, but that should be fixable with a better parameterised algorithm.

Apologies for giving Yet Another answer.

I've not heard this about cars (not saying you're wrong), but I did recently read that lots of motorbikes crash because of exactly this reason - the rider's confidence in the brakes (and in their use of the brakes) is far lower than the capability of the brakes themselves. Anecdotely, I've heard from (older) fellow bikers that 'back in the day' they were told that at higher speeds, they'd lose more speed in an emergency by 'laying the bike down' (falling off then ), as the increased friction area was more effective at slowing a bike than the rubber contact patch of the tyres on the road - all utter bollocks, I'm sure you'll agree.

But it still happens today (riders don't brake effectively enough). I think part of the reason is that ABS is a relatively new concept in bikes, compared to it's introduction in cars. Anyone that knows how to use ABS knows that you simply press the pedal/ pull the lever as hard as you can in an emergency and let the computer do the rest for you.

I got taught Cadence braking when I did my driving lessons in '97. I'm not sure I've ever used it, as I quickly moved into a car that had ABS. Good braking is all about practice, no matter what you drive/ ride.
It's another commonly known thing that bikers are generally (as a group) fairly poor at slow speed manouvring of their bike, which again comes down to a lack of practice. I've been as guilty as the next guy of putting my feet on the floor to do a U-turn, because it's easier, I feel more stable and therefore less likely to drop my pride and joy - it's an instant fail on your riding test though...I know I should find an empty car park and practice the basics, but I don't.

Unfortunately radar itself is limited, Lidar is used for more precise data

So your example is not analogous to a typical AEB event, which I assume would ordinarily be applied if the driver had no time to react - certainly insufficient time to consider all of the elements as you've described?

Are you assuming that you will always have time to assess what you may be running into? Chances are if it's under your nose, the message to your foot to stamp on the brakes will have already been received before your brain analyses the pros vs cons of hitting whatever it may be. Of course you don't expect the car in front to suddenly jam on brakes, or pull out in front of you, or change lanes without bothering to look, or cut you up - but sometimes they do and we have to make allowances for it.

If others aren't driving perfectly, then they will still have / cause accidents - technology or not.

So, we agree then. Yes, of course the real world is different - I'm well aware that drivers who apply this are in a small minority.
