But I suppose your point is more like: we've built lots of completely car-dependent situations in which people live very far from core necessities in life with no way to get them except by car. And that's clearly true. But the answer isn't teleporters or biking in -20 to got 12 miles. The answer is to stop living so far from essential resources. And that doesn't have to mean everyone moving to crazy-dense living around existing resources like grocery stores. It could just as well (better really) mean modest density in mixed areas where we have more medium-size grocery stores so that more people are close to them.
I'm not suggesting individuals just live in car DEPENDENT contexts and then forgo the thing you DEPEND on. I'm suggesting we have drastically fewer car-dependent places.
