"What can ordinary people with busy lives and not a lot of political access do to address this stuff? You can try to address it in your own life. You can try to set up your life so you have to drive as little as possible. In so doing, you vote with your feet and your wallet. When more people bike, walk and use public transit, there is greater pressure on elected officials and government agencies to improve these modes of transportation. It thus increases the profitability of public transit and makes cities more desirable places to live. It also helps reduce your carbon footprint and reduces the amount of money going to automobile manufacturers, oil companies and highway agencies. In a globally connected capitalist world, cities and countries are competing for highly skilled labor—programmers, engineers, scientists, etc. To some degree, these people can live anywhere they want. So San Francisco or my current city in Minnesota aren’t just competing with other U.S. cities but are competing with cities in Europe for the best and brightest talent. Polls and statistics show that more and more skilled people want to live in cities that are walkable, bikeable and have good public transit. Also our population is aging and realizing that they don’t want to be trapped in automobile-oriented retirement communities in Florida or the southwest USA. They also want improved walkability and transit. Finally, there’s been an explosion of obesity in the USA with resulting increases in healthcare costs. Many factors contribute to this but increased amounts of driving and a lack of daily exercise are major factors. City, state and business leaders in the US are increasingly aware of all this. It is part of Gil Peñalosa’s “8-80” message (the former parks commissioner of Bogotá, Colombia) and many other leaders."
