... Until we get driverless RVs, and hordes of retirees roaming the country reinvigorating those rest stops.
In all seriousness, I'm not saying there won't be stop offs and rest stops (because really, who wants to be in a moving box for 3 days), but in terms of feasibility I can definitely theorize a situation where stopping is no longer necessary.
I just finished a road trip and man, would an auto-RV have been amazing. Instead of only catching ~50% of the view because I was the driver, I could take it all in and interact with my lady at the same time vs focused on driving. Growing up I thought RVs were crazy awful - but now I look forward to my auto-RV at age 75 driving my old ass around the country.
