Beijing has huge problems with traffic jams and the CCP has has taken some extreme measures to limit the number of cars there. E.g. they practically don't issue registration numbers for ICE vehicles and there's a queue for EV registration numbers, that currently goes to 2035 (if you join the queue now you'll get a reg number in 2035).
Some cities with heavy traffic in Europe and China have implemented rules, like only cars with even registration numbers are allowed to drive on Mondays.
("Seems impossible, how's that work?" take commuting time and time worked to pay for car, insurance, fuel, and maintenance. Compare worked-time it takes to pay for equivalents on a bicycle, plus bicycle commute time if you removed all the space you drive past that exists only or mainly because of cars [which is... a whole lot when you start analyzing it]. Do same for e.g. the grocery store and other places you regularly visit. You'll probably find that most people in your city—including, perhaps, you—must be losing time to their car, and likely a lot of it, when the point was to get places faster, i.e. to save time. Cars in an environment where lots of people own cars end up being beneficial mainly for the disabled and people who don't have to drive themselves, so can partially reclaim that time for other activities, i.e. the rich. The analysis just gets more lopsided the more complete you try to make it—added healthcare costs, more dedicated time spent exercising to make up for inactivity due to cars, infrastructure costs, et c, there's a lot more time and money that can plausibly be put under the "cost of widespread car ownership" column. And yes, I stole this analysis from Illich—I ran the numbers because it seemed crazy, but he's totally right)
Sure, not anything but if I can be a passenger in the back seat with a driver that's not going to crash, so I don't need to be a second set of eyes for them, or stay awake to help keep them awake, and I can watch a movie or code on my laptop with tethering to my phone, or just take a nap, I could probably put up with a multi-hour commute and I'm sure I'm not the only one.
It may decrease demand for certain types of knowledge work, but the overall volume will increase.
It is very simple, companies invested in EV, FSD, etc... are doing so to make a profit of EV, FSD and etc.
How those affect humanity is not their concern.
Similarly, I worry that if we ever _do_ get fully self-driving EV's it will only serve to make it comfortable to commute from, say, Yosemite to Mountain View - and who wouldn't want that? Yet I rarely see increased congestion come up in discussions about FSD.
