Tesla seem confident it'll be safer in part because of that.
I'm wondering if they've done some something that can lower the front further if an imminent crash is about to happen with a pedestrian to lower the nose even more. Maybe it won't work if you're already at lowest setting, but if you're raised at all maybe.
You think they'd have advertised a feature like that though by now, so maybe not, but I bet they could.
Would be a good feature for any vehicle with air suspension that can detect an imminent crash with a pedestrian
I'm pretty sure Tesla is devoid of any technology that detects pedestrians.
It definitely detects pedestrians: the live on-screen image shows them when they are nearby. They also claim to have automatic emergency braking when it detects pedestrians being in danger. I haven't seen this in action, but then again, I don't drive where pedestrians walk, so... But I can tell that my Tesla does weird short brakings on a motorway when nobody is close. Detects my future ghost, probably.
Their own claim is that their cars are quite a lot safer than USA average: https://www.tesla.com/VehicleSafetyReport -- but I have heard it being rumoured that sometimes companies lie.
I hope you never drive where there are patches of ice on the road.
I do, weekly. These don't happen incredibly often, and they happen only when the cruise control is switched on. Not once have they caused a dangerous situation.
Detecting that collision is on the same order of difficulty as self-driving cars.
This is not true.
Anti collision systems of various sorts have been around for over a decade. The problem space is minuscule compared to self driving, and almost all car manufacturers offer both forward and reverse collision detection at this point.
In fact I think EU is making it a requirement soon.
Detecting a pedestrian where you would want to lower the front vs say a deer or moose (or other vehicle for that matter) where you don't want to lower it is more complicated.
Better to just not build the vehicle out of sharp polygons like it needs to be rendered on a Super Nintendo with FX chip.
You could only enable the lowering in pedestrian heavy areas (city) assuming they legit can't tell a moose apart.
You aren't going to find many moose in downtown NYC ;)
Again, nothing to do with shape, this would be a good feature for any air suspension vehicle that can detect a pedestrian.
Edit: And I'm not sure we need to worry as much about city deer, they are small enough.
Edit: Also if they CAN detect a moose, they should do the opposite and raise the front.
Any car with AEB has this capability which is a lot of cars ya.
I don't know how fast they can lower the vehicle though? There isn't a lot of time between when AEB kicks off to slow you down and the accident.
