> I bet such a system of two-lane, electrified, high-speed, autonomous-steering high capacity vehicles could move as many people as a large multi-lane highway in a smaller footprint all on grid power! To quantify this heavy rail has a route capacity of ~40k people per hour per lane, compared to ~2k for cars (using lower and upper estimates respectively). That means the route capacity for 2 lanes of heavy rail is at a minimum equivalent to a 40 lane highway. https://en.wikipedia.org/wiki/Route_capacity https://en.wikipedia.org/wiki/Route_capacity
