Transportation accounts for around 30% of carbon emissions in the US. We could do a lot worse than rethinking our 'suburban experiment' where many people are forced to use an automobile for things our ancestors could walk to in 5 minutes, to paraphrase Chuck Marohn of Strong Towns.
Having started bike commute (20km round trip), I basically don't want to anything by car. With bike-day people could realize how cool it is to glide at 11 mph without traffic. Things are way closer than they appear if you remove congestion, lights and the obligation to do more distance to reach larger roads people use for fast cars.
free workout, free health, gas savings, pollution free .. it's really something to push
