Europe has been moving in that direction, with an increase in biking, and improvements in biking infrastructure even in countries that weren't traditionally very bike-friendly (like Spain). But it's hard to replicate that in the U.S. because the cities are so much less compact. You would need more than just improvement in roads, but shorter distances, and better transit for the places where you do have longer distances. In the suburb I grew up in, my dad drove 50 miles roundtrip to get to work, the nearest grocery store was 3 miles away, the nearest restaurants/bars were 5 miles away, and there was no transit system at all. So biking tended not to be too popular, except among kids going to friends' houses within the same neighborhood.
