A typical household would have 4-5 people in it and only two cars if you’re lucky. A person needs mobility from the age of roughly 7 to at least 70 for all kinds of reasons.
Please travel the Europe and see how they treat their people and how increased mobility creates a great environment and freedom for everyone. I assure you that it’s not a backwards place as some people claim.
As a side note: All this car craze coincided with baby boomers (roughly) and now that they’re losing their physical and cognitive abilities we’re seeing a lot more accessibility support from them (duh) and I wouldn’t be surprised if they started pushing for free public taxi service for themselves but nothing that would serve the public. And we’re not talking about heavily subsidized industries like cars, but something that can be profitable and worthwhile because it allows people to go to work, school, shopping, hospital, theater, and more.
