Over half? I think you've read my post incorrectly.

I preemptively answered this by saying extended friends and family are a top source of transit.

But yes, walking, bus systems, getting rides, for some demographics, ride shares. Cities like Atlanta and Dallas have low economic mobility because you can't get anywhere except by car.

It’s the buses in Dallas that drive around all day with only the driver. If your on the outskirts sometimes there are two empty buses driving together.
