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, <a href="http://www.nightliner-support.eu/5/our-fleet/" rel="nofollow">http://www.nightliner-support.eu/5/our-fleet/</a> ).<p>Since I don't, I suspect the business travel market isn't there.
If I can spend six hours in a plane and get to the other side of the country, or I can spend 50-ish hours driving, I know which option I'm going to choose.
