I do not know in USA, but in UE norms demand roads to be able to normally operate ad SEVENTH time the expected mean load, so I doubt than an "oversize" car (not big truck) would made significant wearing to public roads. IMVHO the issue is another: we can't sustain cars in cities anymore because there are too much cars for roads and parking infra. There is no "classic" solution for that: cities can only be just public-transport + only needed vehicles (emergency/work-related etc) to work and being NOT designed for such usage they can't easily be adapted => cities are dead end, we can only rebuild them and we already know that since anything change at a certain speed doing such enormous challenge will be pointless, for when it end we will end up in the similar issues for newer/mutated needs and gears. Long story short IMVHO we need some "hub", where people live nearby, BUT little kind an on-purpose only like "this is a place where only students and teachers live for their relative active 'duty', here is just a metallurgic area there are a residential part for workers, but just for their working times and all have relatives and homes elsewhere" etc. Tough to achieve but I see no over evolvable option. So far only moderately dense Rivieras have shown life and sustainability. Low density areas became too expensive, high density untenable. Aside we probably can't sustain anymore entertaining a modern country-wide road network, some countries like Finland here and there have barely admitted something alike, witch means we need something else to move. Small flying drones can be ok for private travel, no I'm not joking, actually a small flying car can cost as a road-born car, on similar scale, the far reduced infra costs compensate extra energy costs BUT that's can work for low weight transports. For logistic is a bit of a nightmare and for that so far I hardly see solutions behind a disperse economy where most of heavy and abundant stuff are local and local only witch is not much achievable. Another is waterways but they are usable only on the sea and large-enough rivers, witch means in too limited spot.
