What seems to be impossible is to locate businesses, their employees, and stores geographically close together. I have lots of friends who drive over an hour each way for work. I used to drive 30 minutes to my job. Now my wife and i work from home and for the first time in my life we have only one car. But there’s no way we could go without a car. Family lives 120 miles away. Groceries are 10 miles, and other necessities are 26 miles. The US was laid out to require personal vehicles. It’s too spread out to have a functioning mass transit system that’s convenient to use.
Using the such a system in the US, even if convenient, has risks. During the peak of COVID, many riders refused to wear masks. There’s no security, no hygiene or conduct standards for riders (try to sit next to a crazy homeless person or someone higher than a kite for 45 minutes), and when you try to get help from law enforcement, nobody shows up.
