I have to turn the pedestrian detection off every time I drive past the local school. Why? The kids figured out that it's really easy to make new cars emergency brake by just pretending to walk onto the road. People suck.

#52Earlier quoted context omitted.
They recognize much more objects on the road but major problem is to do not cause a lot of false alarms. e.g. You don't really want to drive car which decided that plastic bag on the highway is reason for emergency braking, on the other hand is that really plastic bag or some drunk person who is sleeping on the road... I remember when Volvo introduced IntelliSafe technology few years ago that car was totally "paranoi…
If it's confused between a plastic bag and a human, it hasn't recognised it.
It didn't recognize a plastic bag as a human, it recognized a plastic bag as an unknown object. A solid object the size of a plastic bag could cause a major accident.

#53Virtually eliminating pedestrian fatalities could be quite simple, but we don't do it because it would inconvenience people: Set a 30 km/h (18 mph) speed limit everywhere but controlled-access freeways, and enforce it strictly. At 30km/h a car-pedestrian collision is almost always non-fatal[1], and at that speed cars can stop almost instantaneously.

The good news is that cities are starting to finally do this. Slowly, but it is happening.

You should be a more defensive driver. This sort of attitude could lead to you seriously hurting someone.
Re: Six cars aced new pedestrian detection tests
#56I think the interesting thing in that article is the stat that pedestrian fatalities reached their lowest in 2009, and have been increasing since. Is it really (as I've heard and read) that it's because people are on their phones and walking out into the road? I've definitely seen people do this in front of me, but I know that's merely anecdotal.
I remember reading an article on hn that the rise of SUV's and their design is related to the increase of fatalities. Like, compare a pedestrian collision where the car has a lower and more aerodynamic front vs the wall that is a SUV's front.
SUVs are higher and hitting people in the head / chest -

Ideally some 'low light camera' should warn you that in darkness far ahead there's 'something' unusual on the road and you will have time to react. Recently there was accident where truck with palm oil overturned on highway and first cars crashed into the truck because they were travelling too fast and only with low beam lights : https://www.youtube.com/watch?v=igX765Vw1fY For example this camera module will be used…
Adding thermal imaging to the sensor suite would probably help with a lot of edge cases, but the hardware is still very expensive. It has come down some in the last 5-10 years but there is a long way to go.
The necessary sensors are really expensive, and that's why the production cars from Tesla and GM and such just aren't that great at it.

That means halving the bandwidth of all inner-city roads (that are traditionally at 35mph+)
If a road used to carry 1000-cars per hour, it will only carry 500-cars per hour if you drop the speed limit from 35 -> 18. Effectively doubling the length of time for congestion.
You can get around this by building twice as many roads I guess, but cities don't really have any more room.
Re: Six cars aced new pedestrian detection tests
#59Basically none of them are good enough for a real world scenario in a busy city. But they may save life on some scenarios which is good. They can achieve a huge safety improvement by forcing speed limit. But somehow car manufacturers don’t want to implement it.
Not exactlty the same thing, but Volvo has stated they plan to limit the top speed of all their cars to 180km/h

What sort of attitude? Could you be more specific? Turning the pedestrian detection off in that specific area is defensive driving, I don't want to get rear-ended because someone maliciously triggers it.
I live in an extremely busy city full of scooters (of all kinds!) and drunk pedestrians, it's not possible to get far here without extreme care.
