My father's a civil engineer, and has told me they've been trying to do this since the 70s. The original plans were to put a magnetic strip beneath one lane of our freeways that could allow simple lane-keeping and some basic communication to keep the cars properly spaced, then raise the speed limit up 100+ mph for those lanes. The problem is, once you ask anything of government infrastructure, it may take forever. I could maybe see it eventually happening if these companies lobby heavily for toll lanes, where autonomous zero-passenger vehicles pay the bulk of the fees.
