Maybe try it before write that? If you are from USA then Waymo already is company that has self-driving cars on street in operation.
It is much easier at the begining to create safe slow speed vehicles and fixed route vehicles.

A couple of things about Waymo's Phoenix experiment. First off they selected Phoenix because Phoenix is literally a desert. Good weather conditions most of the time, good road conditions and low traffic. Second off, they do put a human safety driver in their cars. When it's raining, the human takes control. When there is a pothole on the road, the human takes control. When there is a construction zone, the human takes control. When there is a complex parking lot, the human takes control. When there is anything unexpected or difficult for the car, the human takes control. While it is some impressive technology, it's not yet ready for release into the wild on its own.

The problem with "the human takes control" is that the human has nothing to do most of the time. He is effectively a passenger even though he is sitting behind the steering wheel. Then suddenly, without notice, he must put himself instantly into the mindset of a driver. That's asking a lot of human nature.

On the contrary. I was raised to listen and think and learn from others before judge them and respect elders that i benefit from(while newborns are our future who built the society for them?) and they benefit in return(symbiotic relationship)(but i am doing it also because i have heart). And i am doing it. I don't have prejudice toward anyone as long as those elderly respect me in return.

For example there were|are some famous people like Dan Pena and George Carlin and other who teach younger generations how to live but unlike some people here they do not attack people themselves but simply state and share lessons from life and argue against POVs. This is what i was|am doing. Unless i am provoced or insulted i do not use such bully methods but try to resolve conflicts peacefully.

It took me long to come to this thread. I'd like to contribute with a few things.

Back in 1985 I knew the first automated metro network in Europe. It was at Lille, France (the first one in the world was somewhere in Japan). I did stay there for about 10 days as I had some friends in the Lille University, students and teachers. One of them was among the staff of a robotics laboratory and was somehow involved in the setup of the system. Of course, a metro line is perhaps much easier to make, because the line is fixed and closed. However, big part of the line wasn't underground. This means that there is always a risk of objects on the tracks, because of the wind. Electronics and I.T. were provided by Motorola. The setup of the system was rather hard to complete. During several months problems arose all the time, with passengers on board. Of course these problems/software bugs weren't dangerous for the passengers, nevertheless they could become very annoying. In some cases they were forced to "reset" the system. Do you remember that magic "reset" button that will restart the computer when everything is stopped? In the case of the metro this meant that the trains had to remain at their positions, usually not at some stations, closed doors with their passengers inside, and the system started to real-time simulate the network since the first station up to the current positions. This could take quite long, say 45 minutes or more, with nothing else to do. At the time of my visit it seems that major issues were solved. I remember that the driver's room was simply empty. I remember to see often some Motorola technicians in the passengers area, wearing their uniforms. At the time the "technology peak" was perhaps 68000 and similar processors. Next project for the robotics laboratory would be the tramway without driver! This is much harder than a metro line, because a tramway circulates in the streets of the town, with other vehicles as well as people. I don't know what finally happened with this project.

On the other hand I learned that there can always be problems that designers didn't think about. Such a case was a contract with a chocolate company for a robotic system able to take chocolate pieces from a table and put them in boxes. Some months later the system prototype was ready for presentation to the client. Unfortunately it was summer, the temperature was quite high, the chocolates became very soft and the robotic hands couldn't keep the pieces as they were easily deformed, falling down!! Big success :P

About self-driving cars, I'm afraid that finally the simplest solution will be given: humans would be forced to stay away from the car's way. Machines are never wrong (especially if they belong to big companies )
