And can be more of a hassle or less conveniently located than a transit stop.
And then one day I realized some of the buildings were multi story parking structures and it kind of made me mad. So much of the city infrastructure is whored out to the needs of arrogant, obtuse car people, very much at the expense of everyone. It brings quality of life down and cost of living up for absolutely everyone because of people wanting the right to drive their own damn car everywhere, no exceptions.
And I stopped looking on them with pity or sympathy and started looking on them as parasites who totally deserved whatever small misery they were inflicting on themselves with driving around, looking for parking. But I did not deserve the misery they were inflicting on me with things like worse air pollution.
Combine the two and you get a self driving car to central location > car or public transit to city center > self driving car in the city. Remember parking is often 10+$ a day due to land value, so two ~4$ trips can be a net savings.
Finally, even a 20-30% drop in demand would be huge in such a capital intense industry.
