Good points, but you still have the fundamental physics problem of hauling too much mass for too much distance for too little gain (1s kgs of groceries, etc).

Good points, but you still have the fundamental physics problem of hauling too much mass for too much distance for too little gain (1s kgs of groceries, etc). The US needs to get as many people off the road as possible. Get them on to bicycles (e-bikes), walking, riding buses and trains. I am looking at America's balance sheet and the only thing cars do is blow a whole in it. Cars cost too much relative to cash flow generated for families. Cars take up too much space in cities, killing cash flow generated from sales taxes and property taxes. The Return on Assets from a car is just too low, I believe the rate falls below the US gov/state govs cost of capital (hand wavy-speaking).
