It’s time for Americans to embrace small cars

This is a most excellent place for technology news and articles.
It's more complex than that.
The way the US is spread out makes public transit prohibitively expensive and difficult to achieve proper coverage. To make it effective, you would have to shift the entire way we live. Our entire society is built off the concept that everyone has a car.
Add to the fact that building transit is extra expensive in the US and you arrive at the reality that we will NEVER have a working transit system. That's why the shift to small cars is needed. We don't have any more room for roads, so we need more cars to fit in the roads we have
In fairness the Interstate system was more about air defense than transit.
Politically you have to get several different groups of people to buy in to make it work. Unfortunately "what it's about" is the deciding factor in accomplishment.
