Why are we’all in such a rush, anyway? If you need to talk to someone right away, we got video conferencing. If you, in an emergency, really need to move somewhere fast, there’s helicopters. I say we just consign the whole ‘car’ idea to the dustbin of history, and just convert everything over to canals. If some insist on speed, we can consider adding a train system. But the only means of private mechanized transport must be by watercraft! That should be enough.
You vastly underestimate just how many locks I am willing to build!
Won’t the cement usage needed create mass amounts of heat dispersal thus accelerating global warming during the transition?
Side note. I wonder how much water it would take. I’m sure we could slowly get the salt out and use fresh water most places, otherwise we would kill all ability to grow plantlife in surrounding areas.
