Cancel the bullet train, and instead plow all that money into rapidly deploying this. There was a period before cars where trains were the most efficient form of long distance travel, so cities were built around this fact. Then cars got popular, so we built cities for those. Then they pushed light rail to combat suburban sprawl. It would be funny if automation made cars the ideal mode of travel again.
