At least one of those is far closer to reality than the other.

  While that's true, the less flippant question is whether fully autonomous cars -- where "fully autonomous" is defined as being able to climb in one, kick back and do your work with no concern the way you conceivably could on a train -- will (a) exist, (b) be road-legal, (c) be widely available, and (d) be generally affordable within a timeframe that makes a high-speed rail line moot. I don't think that's remotely a given.

    We're going to have autonomous cars that can drive SF-LA long before we have high-speed rail. Self-driving cars from the big players are planned for the 2020-2021 model years.

      I have this weird feeling that before we have many of them in mass production, we'll have a single car that fits this description.
