I'm not sure why you've been downvoted at the time of my commenting; but you've probably upset someone who deserves to be upset. The sheer amount of space that is killed off in many cities to support roads and car parking is insane. If there wasn't that much dead space, walking around would be more than feasible.

Car-centric design sits in competition with pedestrian-centric design, and the bias towards road over-construction has ruined a lot of urban spaces. At the very least, rolling back government involvement in road construction would be helpful.
