They dont. This technology, aside from being infeasible at the level it would need to be to bring the claimed benefits, doesn't actually even have real benefits worth this dangerous development. If anything its a desperate attempt to keep private automobiles as the primary transportation system despite more communal, and public, systems being superior. Its also a USian obsession. Some other places have been able to actually invest in superior public infrastructure but the US is so focused on techno-solutionism it, as usual, misses the extant and superior solutions. Self driving does nothing to mitigate the sprawl and atomization that wreaks havok on our society, but trains and busses, and density that cannot be achieved with car-dependence does.
