Why? You think we should be moving around in open air? Or you think we should all be moving though high density channels like trains?
I don't see what's wrong with cars if they are minimally heavy, aerodynamic, and managed as a fleet. Busses are certainly not better. And trains only solve half of the problem. (Thoroughfares.)
I absolutely adore the bubble people on HN live in sometimes. 99.99% of people in the world are not computer engineers who have the luxury of doing their jobs from anywhere(including home). It takes a day of interacting with people in the real world(instead of reading about them on the internet) to realize that no, daily transportation to and from jobs is not going absolutely anywhere.
And this is not meant to be a personal attack on you - just an observation of a very common sentiment displayed by many HN users.
Taking the top 3 most common professions here in Sweden by a large margin: sales, education and health care.
Every year sales are converting into online sales. computer engineers and sale people go to the same office buildings, sit at similar desk at similar computers.
Education is also converting into online education. Self study is increasing in practically all levels, and the cost of buildings and class rooms could be saved to pay for more teachers.
Health care is similar transforming. A lot of primary care is done online to save costs and to filter out cases that actually need a doctor visit. Telepresence is also creeping up for elder care. In theory this pay for more doctors.
So slowly the 99.99% of people of world are doing jobs which from a mechanical view is identical to computer engineers. Travel from home, enter office, do work, go home.
Not nessesarily. Driving is one of the most common tasks worldwide, so it makes economic sense to pour large amounts of resources into automating it. Beyond sensors and computer components it also doesn't require any new hardware.
Most forms of cheap labor in the West don't fit that description.
