Public transit is obviously one facet here. But another is just flat out poor urban planning in the U.S. Walking and bicycling should be more viable forms of transportation. But there are only a small handful of cities (arguably just one) where that's currently feasible in the U.S. It's pretty ridiculous that we've spent the past 100 years designing our cities around the least efficient, least pleasant, most dangerous form of transportation in existence. Like you, self-driving and electric cars don't interest me a whole lot—I feel like they're largely missing the point.
