You realize books exist, right? Or any other media you'd be consuming sitting down at home anyway?
No it doesn't. If it takes an hour by bus or 30 minutes by car, that 1 hour is more useful to me and way less stress. Until I didn't have to drive every day due to Covid, I didn't realize how costly driving, especially in traffic or long distances, was to my mental health.
It sounds like you're not able to take advantage of the Internet on your smartphone to the same degree as I am. Between the web browser, and all the apps, especially Gmail, there's enough there that I can take care of some chores/errands. I'm not talking about burning time on social media, though that's certainly available. With hotspot functionality, I'm able to do real work on my laptop, anywhere there's cellphone service and also some company shuttles have wifi.
Look, cars are luxuriously convenient but having to drive isn't. We have Stockholm syndrome with it, and think it's a good deal. But we're commenting on an article about self driving cars because it isn't.
Personally, I don't spend that much time "plugged in" to my phone these days. I don't have social media (HN is as close as it gets), and I keep most of my e-socializing to group messages between various friend groups on signal. So an hour on a train/bus/etc would likely be too much downtime for me.
I do have an uncle who lives in Chicago, at the end of the line, train wise, so, it's over an hour to get into the city. He just catches the train and goes to sleep, because he's riding the whole thing to the end, sets an alarm, earbuds in, +1hour nap. Nice side benefit, but, truth is, he'd drive if he could, but the way chicago is laid out, he'd be walking a half mile from parking, and it's only like a 2 block walk from the end of the line to get to his work, so, makes alot of sense for him. For most, makes zero sense.
Understand that, time is the only truly non-renewable resource. Everything else can be replaced, somehow, someway, but time is irreplaceable. Ultimately, if you're going to have universally viable public transport, it needs to be clean, safe, comfortable, and at least as fast as owning a car. So far, after decades of advancement, it's still none of those things for most people.
