It’s mostly like taking an Uber, but I think the future will have many more instant-car users, since it is so convenient in major cities.
There are benefits of course, a self driving taxi could show up configured to your exact specifications, would probably be a more standard/reliable experience than Uber, no need to interact with people if you don’t feel like it, and no need to consider them either. Play loud music or sit in silence. Make a private call. Sleep.
Relatively minor benefits in the big picture but it’s mainly that I don’t see Apple hiring a bunch of drivers, so I think a self driving fleet could be the dream. They’re big on UX control, kinda their signature.
I think a lot of people overestimate how much of a cost uplift comes from having a ~minimum wage driver piloting the vehicle. Been a while since I looked at the numbers but say you could cut the prices of an Uber by about 50% per mile--which is the ballpark number--how many people would give up their cars outside of dense cities if they haven't already done so. (Assuming they can buy autonomous vehicles themselves.)
I think if autonomous cars are much cheaper than Uber it could push some people to get rid of their car due to cost, but personally I would never do that since a cheap car isn't a huge expense.
