Autonomous cars are wildly inefficient compared to high-speed rail and would likely require similar sized infrastructure upgrades and ongoing maintenance in order to operate at scale. Assuming the 20 year timeline us actually feasible, their better suited for short distance trace anyway. I generally agree that one-off projects are a bad investment and that we should be building a nationwide network of high speed rail. But your original comment was to the broader concern of high speed rail’s viability relative to the size of the IIS.
