That makes sense for people in dense urban areas, but millions of people live in suburban areas, smaller cities and town, and rural areas. Or need to go visit those areas. (reading your other comments shows you agree, but I will continue on none-the-less)
I completely agree that an automated system where you pay a monthly fee to have a car pick you up and take you to work or lunch or whatever makes a lot of sense for a lot of people. But not for a lot of others, so I think the demise of private ownership is a bit premature. Just like on demand services hasn’t completely destroyed DVD, CD, and now ever increased record sales.
Plus, especially in America, people are in love with their cars. Where are they going to put their Doctor Who and Star Wars stickers? People practically and literally live in them, some times. I have the exact specific super safe car seat in mine, plus all of my emergency stuff in the trunk, my cane and umbrella I rarely use, but want there if I need them, my kids gum, her tissue box, etc. Plus my kid lives 8 min from me. I won’t want to wait 10 min or 5 min or any lead time to pop in and go over if I need to.
Maybe I just have bad luck, but I have had electric problems - simple ones, relatively - in my cars over the years. Last one was something in the wiper/blinker stick not working right, blinking hazards constantly, and burning something with the brakes applied.
But I dunno, I guess there would be fewer accidents thus fewer new cars. But people often buy new cars because they want new cars. Not just from vanity, but because newer cars are nicer. Just like anything else, computers, phones, TVs, or anything else you use every day. I seem to be a dinosaur living in the “drive it until it dies” department.
