I would love public transportation like I've experienced it in Europe, but train tracks have exceptionally tight tolerances and high costs to build/maintain vs. roads. I hope Musk will fix this, but probably not before "good enough" self-driving cars arrive. Also, trains get into accidents pretty regularly. First Google hit:

According to the US Department of Transportation, there are about 5,800 train-car crashes each year in the United States, most of which occur at railroad crossings. These accidents cause 600 deaths and injure about 2,300.
