Not just modified vehicles or hummers, but a road filled with SUVs, minivans, delivery trucks, crossovers. Even a "standard" Ford F150 is goliath, and an indestructable frame won't save you. To the contrary, a super-rigid frame translates into occupant injury. Crumple zones, energy absorbing materials, deformation of structures = survivability. A 20 mph head-on collision in a 1950s auto with a full frame design is often far more serious than a 40 mph collision in a modern auto. Head-to-head comparison: https://www.youtube.com/watch?v=fPF4fBGNK0U (likely death vs possible foot injury)

Now contemplate a 6' long vehicle with 1' or less of "crumple zone".

Where I live people are on bikes, ebikes, escooters and cargo bikes all over the roads anyway so this fits right in.

I drove through Texas in a small Kia once, indeed, I was always afraid someone would fail to notice me and drive over the car thinking "what was that?"
