Useful information for driving are communicated through images in form of road signs, traffic signals etc.
I’ve always wanted a car that shows my speed and the relative speed (+/-) of the car in front of me. My car’s cruise control can maintain a set distance so obviously it’s capable of it but it doesn’t show it.
I said the relative speed. If the car is going the same speed as me then the relative speed is 0mph. I want to see that when I’m not using cruise control.
The models that drive these cars clearly either have some more evolution to do or for us to design the world more to their liking.
> They probably did some cost analysis and realised it's not worth spending engineering effort on other modes when human drivers are able to drive around pretty much using only vision.
Humans and cars aren't equal so this is just incredibly misguided as a principle.
