I think this is a really great idea. Traffic and congestion have gotten so bad in so many cities that it's faster to walk. A lot of people would too but a lot of these cities aren't "walkable" cities. I remember trying that to avoid a traffic jam and by the time I got to where I was going, I felt like I inhaled a year's worth of carbon emissions and that my blouse is now beige instead of white. Lol.
