Hi Dr. Albert E. Patterson, I'm looking into the futuristic design of Autonomous Refueling/Recharging System (ARRS) for autonomous cars such as the Driverless Taxi in Tokyo. You don't expect the passenger to get out and manually refuel the Driverless Taxi. Please tell us your knowledge about the Autonomous Vehicle System Design.

I conclude that the idea that one can transfer control of the almost autonomous vehicle to the human occupant when the going gets too complicated for the system is fatally flawed. Driving skill assumptions about the hapless occupant are bound to be inaccurate and far lower than a well designed electronic system. If the situation is starkly perilous, the "operator" may well have fainted dead away. The closer the development process gets to the completely autonomous (level 5) design, the more insurmountable the handover. Even a moderately well designed level 5 system will be able to outperform 99% of the anticipated human operators. The user experience in the autonomous vehicle will, of necessity, be that of a train ride with no user concern for the technical or practical matters of the vehicle. The user experience in the almost autonomous (level 4.8 or so) vehicle may be so disconcerting as to prevent anyone who is informed of the control transfer situation from acquiring such a vehicle, or taking a ride taxi style.
