> in service of the development of modern subterranean transportation
It's not really that, it's a weird parody of "modern subterranean transportation". They could do interesting things with it, but right now it's just private roads. It isn't more efficient than a subway, it isn't more flexible, but it's likely more dangerous.
Cant wait for one of those cars to cook off it's battery pack possibly leading to the car behind it cooking off it's battery pack. And where do the humans in those cars go? Last time I looked at the press around this thing the tunnel is barely wider than the cars. Add fire and smoke and it's just a lot of dead people.
