Hey man, if we’re rebuilding roads for the sake of self driving cars, let’s just go back to ubiquitous light rail instead, like we had before cars got popular. This whole self-driving industry is so ridiculous when you consider that this has been a solved problem for over a hundred years..

The problem is rail is horrible at traffic handling and uses time multiplexing. One guilded age unethical activity was deliberately creating "traffic jams" on competitor's lines. While rail is good and could use expansion it makes a dubious complete replacement. It works wonderfully with shared routes but fails at handling the "amalgamation" part.

Even Japan still uses trucks for the last mile and they have embraced it enough to have "bullet train suburbs" around stations.
