Just because an RV is smaller than a house doesn't mean it's the right choice. If resource depletion and environmental harm are the issue a small super efficient stationary dwelling is the answer. Each person would concentrate on consuming as little as possible and an RV is a long way from that.
No one would joy ride, or travel around in any vehicle just to look at different places. No one would race cars or boats or anything else to see who can go faster and faster. If you really want to do something about every day transportation you wouldn't build zero to sixty in 3.5 second EV that most people can't afford and then force them to subsidize them.
People blab on about GW but knock any EV that doesn't haul tail. Total phony bs show. If you actually adapt concepts and ideas or many of the proposals you would be shocked at how you would be living.
Finding new ways to keep using more doesn't sound like the right thing to do.
