I don't think driving will be banned, there is a lot of people who like to drive.
But I say there could be roads that certain lanes would be no driver but the speed limit could be much higher e.g. >150mph. The tech could drastically reduce times. Driverless could be a major advantage, as for black ice cars would know the temp of the road and reduce speed accordingly...
Trucks could end up being more like trains with only one person leading out many trucks... Even rural roads can be self drive, it just about the technology which will
The tech will get a lot cheaper in next ten years. Europe are making Electric Cars cheaper from a tax point of view...
Roads are designed with maximum speed in most locations. A self-driving car might run 150 mph with no other cars on the road on rural interstates that are mostly straight. Try to imagine driving at 150mph through West Virginia where sometimes curves on Interstate 64 at 45 mph cause you to have a significant pucker factor.
You apparently know nothing about "black ice". Black ice, freezing rain, sleet and snow can all occur at the exact same temperature.
A self-driving car would most likely be electric and it would never have the power to maintain that speed of very long.
Electrics cars can now drive hundreds of miles between charges. Unless there was some emergency, they would not be driving 150 mph, unless it was an open, straight road.
As the technology improves, almost at the instant the wheels lost traction, the car would respond. And respond properly every time. One advantage a self-driving car would have is that the computer does not get impatient like a driver does. Nor does it get fatigued. And current models of EVs have sensors and cameras that can tell
exactly how far away the cars are in front of it, behind it, and all around. And it does this simultaneously. Unlike human drivers, who
should scan their mirrors every 3 to 5 second, but most don't.
