I'm someone who's a skeptic that Lvl 5 autonomy will ever really exist and work, but if anyone even gets to a solid, reliable, far reaching Lvl4 it'll absolutely be China. In part because it's going to require newly designed, built, and maintained infrastructure and city design that's fit for purpose. America will start a nuclear war before agreeing any substantial investment in it's own infrastructure.
