Investigate investment in railways
I suggest conducting a cost benifit analysis of significantly investing in railway improvment. It is possible in most of europe, Germany in particular, to take a train to pretty much anywhere you would want to go in a timely manner. Even to small towns. It creates an enviornment where personal cars are truely optional for most of the population. Many of the trains are run with electricity. I concede there may be geographic, financial, or other bariers that would make such an extensive system in the United States unfeasable but the benefits to productivity, the enviornment, national security (hard to drive a train into a building), and population congestion seem large. We should make sure we aren't overlooking a good opportunity.
