And are only needed 1% of the time. The Cybercab is small and lightweight so it has less impact on 'infrastructure' than typical cars, and it's very efficient too.
Public transport superior in every way? My small city is proud of their bus service which connects to the next city 20 km (12 miles) away where many people work. So the other day I was walking into town to get a haircut (only 2.5 km away, so why take the car when it's a nice day?) when I saw two buses go by. One had 1 passenger and other had 3, as they roared along belching out diesel fumes. This is by no means an uncommon sight.
Trouble is they have a timetable to keep and people would rightly get upset if they delayed or cancelled runs because there weren't enough passengers. Even then the times don't suit a lot of people, including my brother when he worked in the other city. Meanwile the highway is clogged up with angry drivers trying to get to and from work every day. My brother used to leave home an hour earlier just to avoid the traffic.
Your assertion that autonomous taxis are a
psyop is ridiculous. They are a service that people can use if they want or not if they don't. Most don't. Tesla hopes to offer that service cheaper, which means more people
might be attracted to it - or not if they don't want it. Nobody is being influenced to use a robotaxi any more than any other product or service in our consumer society. Probably a lot less actually. Tesla famously doesn't promote their products with high-pressure advertising like most others do.
You could say that Musk's antics are a kind of advertising, in the 'all publicity is good publicity' vein. Question is will his 'utopian vision' attract more or repel more? I suppose it depends on the ratio of embracers of new technologies to Luddites and partisans.
