Self driving cars has been in the news, everywhere, either developing some self-driving featurs or designing self-driving cars from scratch. Features like lane control are mostly nuance, auto-braking is useful and will wake up the driver for sure. Before a truly "auto" mode is available, siping a glass of wine is not advised.
What's common of nothing in common of self-driving cars under development is they don't talk, to each other or to the surroundings. Tesler would not talk to Google car, and they wont talk to the traffic lights either. A driver behind the wheele controls the car with its capabilities in mind, watch other cars around, reading signs, mapping the routs in mind, well, besides planning for the kid's soccer game.
Computers in the self-driving cars are as good as what's being fed into them from radar detectors and cameras in the peripherals of the car. Human eyes sees a lot more, human brains accumulate a lot more than the radars and cameras can capture. If a route is under construction on Moday morning, it will still be on Monday evening, Tuesday morning, etc. Some loose pieces are flying off from the back of the truck in front of you, see it, avoid it. The Mustang behind you is aggressive.
The on-board computers need to "see" more to be fully "humanized", or to drive as good as a good driver suppose to be. You can read this piece from anywhere and on any hardware without worrying how it auto-pilots itself to your screen: sets standardized protocols are in place so the article can travel safely on the internet, no collision, no loss (well, right). Say internet addresse is assigned to a MAC ID according to IPv4 or IPv6, which should find their way into the self-driving world, like Driving Protocol Version 0 or DPv0.
DPv0 confers all capabilities of the car, built in (hp, sedan, truck, etc), assigned (heading to GPS coordinates by what time frame, etc.); of all traffic lights on the route; of road signs (steel plate, open ditch till tomorrow morning); of major events like a football game.
As much as you like your privacy, a self-driving car need to learn everything from all of the DPv0 capable "devices" en route in order to carry you to you GPS coordinate, safely.
