Assuming you can charge at home for daily driving …. A map of superchargers looks like it covers at least the interstates decently . Sure, there’s less covered areas, and not as frequently as rest areas and may be crowded , and away from interstates a few less populated areas are poorly covered but t seems like 90+% of US population ought to be able to road trip.
It really seems like charging from home is the more important issue to address, since it does make a huge difference. There are way too many apartments and condos where there is no incentive to provide charging, even if the tenants want it. We need more incentives plus find a way for them to see the need
