This reminds me of the Fredrick Pohl line "A good science fiction story should be able to predict not the automobile but the traffic jam."
So I wonder what the traffic jam is going to look like given that the car seems to already be parked outside with the engine running.
Faster depopulation across the developed world? Probably, but maybe there's something even more important.
I'd put what the author describes into the category of "pleasure trip," which is what the car was mainly used for initially.
As infrastructure to support the car was built, it became a necessity. And that's what created the traffic jam: network effect. The suburb and the car fed on each other. You don't get a traffic jam worth talking about without a suburb and a network effect.
So I'm curious about the network effects something like an AI friend might have. What kinds of new infrastructure and new lifestyles will they enable/encourage? And how will this infrastructure fuel future demand?
