Self-driving cars don’t really do much to increase density of moving people or decrease infrastructure costs per-passenger-mile.

Some parking needs may be reduced, but you still need somewhere for the cars to hang out while waiting for each morning and afternoon directional commuter rush.

You still need the same number of freeways with ever expanding lanes.

They mostly decrease the monetary, time, and mental cost of taking a car to work as an individual choice, which will increase the load on roads and freeways.

How many passengers per hour does that train line move, versus the costs to build and maintain an equivalent capacity freeway with one person in each car?
