If long-haul driverless travel were so useful for business travellers, I would expect to see more rich people in chauffeured RVs or buses, rather like how bands on tour have a sleeper bus with beds and showers (eg, http://www.nightliner-support.eu/5/our-fleet/ http://www.nightliner-support.eu/5/our-fleet/ ). Since I don't, I suspect the business travel market isn't there.
