&quot;Self driving&quot; cars which require a human to be ready to take over are totally plausible in that time frame...<p>But are you suggesting that in 5 years a person can summon an autonomous taxi in the Bay area?  By autonomous car I mean the client (passenger) will not need to be ready to take control nor will there be any other human in the vehicle for that purpose, and the vehicle will transport the client from one place in the Bay to another over the public road system, mixing with other non-autonomous traffic of various types.<p>If so, I&#x27;m in for USD $100.  I say that in 5 years (12&#x2F;17&#x2F;2020 or before) it will NOT be the case that a user can expect to summon an autonomous (as defined above) taxi for transport anywhere in the United States.
