I have about 250,000 miles riding on the road... but very little for transportation. I think in the US it would be tough to sell the idea of everyone using bicycles for transportation (weather, hills), but we need to get away from driving monster pickups and SUVs everywhere. I've been proposing that we make a tiny car standard (< 500 lb for instance, so really small), and repurpose urban infrastructure to make them safe and convenient. This would be far safer for cyclists and pedestrians as well.
It's a perfect match for electric vehicle tech, since simplicity is important in a small vehicle if you want it to be affordable, and a small battery would suffice since they are very efficient and don't need a long range.
