Forcing people to be pedestrians would be likely a significant improvement for their health and quality of life.
As an American in a major city, the alternative sucks. I'm forced to be a driver, car costs eat a significant portion of my income, my neighborhood doesn't even have sidewalks between the residences and shops (which are across a highway that has a cross walk with no sidewalk leading up to it), and I end up having to drive at least 5 hours every week just to work and get my kids to and from school. This increases pollution in my city and comes with a regular risk of injury and death from a car accident, which is one of the leading causes of preventable death.
I'd rather be forced to be a pedestrian than a driver. Having the choice would really be great.
