> improving road design with knowledge we already have. Smaller roads with fewer lanes and lower speeds are very unpopular among car enthusiasts. > Figure out how to get trains to operate everywhere instead of only on fixed routes Cars can't operate everywhere so this is a unrealistic requirement in the first place. > Do the environmental math on that -- how full does a bus need to be before the pollution per passenger is better than a compact car with one passenger? How about a compact car with four passengers? Assuming a 1 person/car with a average 19mpg, and a average bus 6.2mpg, you need 3.06 people on a bus before it breaks even. If you can have 4 people on a compact car with four passengers, you can have a bus with 3 people on it.
