It's not a wasteful when US has huge land and those fuel vehicles need to travel a long distance may encounter car accidents e.g. fatigue, winter, floods, would be benefits from reduce air pollution in the these concept tunnel, in contrast, the size of Singapore is a lot smaller.
The tunnels could use solar energy which is not wasteful.
Uh... if the solar energy could be better used elsewhere, you're still wasting energy. We're not post-scarcity yet.
Actually it's the land use on roads and parking which is most wasteful. Maybe we could solve half the problem with this, even if it is boring.
