Because . . .
There's no way their OS will ever be hacked.
Computer systems are infallible.
Electrical systems are fool-proof.
Our electrical grid is safe, secure, and virtually limitless.
Nothing is perfect. And yet air traffic control has been computerized for decades and air travel is incredibly safe. Large passenger Planes regularly fly on autopilot their entire flights. Elevators are automated and yet we seldom hear of an elevator death... Several commuter train systems are completely automated, and all depend upon computer control of traffic.
The current human driven cars and trucks are so safe? In the US alone, According to data compiled by the National Highway Traffic Safety Administration (NHTSA), in 2016, 37,461 people were killed in 34,436 crashes, an average of 102[1] per day.
Around the world; Nearly 1.3 million people die in road crashes each year, on average 3,287 deaths a day. An additional 20-50 million are injured or disabled. More than half of all road traffic deaths occur among young adults ages 15-44. Automated cars will probably not completely eliminate accidents. But the improvement over the current plague of traffic deaths will be enormous.
No, electrical systems are not fool proof. Neither are pipelines or tanker trucks and trains distributing fuel. When pipelines fail, they pollute. When tankers crash, they kill. When electrical systems fail there can be consequences, but never to the extent that oil tankers can..And with tankers its almost always human error.
https://en.wikipedia.org/wiki/Lac-M%C3% ... l_disasterThe electrical grid is undergoing revolutionary changes based upon the experience of the architecture of the Internet and the vast improvements in both generation of electricity through renewable sources and the the cascading improvements in storage .
Its possible that many charging stations can be constructed right off the grid. That's how many of the rural communities in places like India, still without electricity, are gaining electrical service. Tesla already provides 100% of an American Samoan islands' electricity through solar and Tesla power pack batteries...
People with a lot more experience, knowledge, expertise and education then you have, have worked this out Fate. When companies like GM and Ford are moving their massive corporations towards electrical self driving cars, they concluded it is not only possible but optimum.
You are just an addled old man shaking his fist at the clouds...
