The simple action proposed was to not drive if your journey is under 10 miles. I don't think it was ever suggested that this would solve all our problems. Just that, if you can avoid contributing to the pollution, then maybe you should consider not contributing if you are an able-bodied person who could as easily bike that distance. Most car journeys are under 5 miles. Imagine the benefit if the majority of these journeys were made by bicycle instead! Public health from less air pollution and more exercise. Less stress, less traffic, less potential for vehicle accidents. Governments might even decide to improve pedestrian/cycling/public transit infrastructure and turn car parks into people parks with green spaces (which would reduce absorption of solar radiation and cool your city and clean its air). It's a really simple proposal with many obvious benefits and no clear downside whatsoever. And just because it isn't a silver bullet you are all up in arms against it? Tell us more how BrianHenryIE is the actual source of the problem here and how you should still drive everywhere because of his equivalence to 100 farmers...
