Walking doesn't seem like a problem that needs a solution to me. I imagine cars being used when you are too pressed for time to walk. The problem is that you are making too many commitments for yourself, not the walking part.

A bit hyperbolic, but this type of argument can be made for pretty much any disruptive technology that allows humans to overcome physical limits in order to make more choices about how they spend their time.

I like to think of it as flying versus taking the train. I don't think anyone prefers the experience of flying economy to a romantic first-class cabin on a train, but they do it anyways because it saves time and money that they can spend on things they consider more important.
