Agreed. It’s insane to have our roadways up where they are subject to the elements like this. Especially with the tunneling machines we have today.
It’s coming together. We couldn’t use the air-breathers in an enclosed place anyway.
But with dual-mode vehicles, both electric and internal combustion, all that is needed for tunnel operations is a means of tapping into the road power.
Next is full auto with autopilot. Smart grid, smart roads.
Your dog could drive. Don’t let him have the keys.
