Autonomous Vehicles, LEAF and others...

During the event it will showcase autonomous driving with the NSC-2015 prototype (pictured), a modified version of the Nissan LEAF.
The car will use a remote monitoring system to recognise the surrounding environment thanks to an all-around view camera and 4G communications. It will be different from a system that uses a GPS to establish a car’s exact location because it will provide precise recognition of the surrounding environment: even when underground.
When the driver exits the NSC-2015 it will start to park itself automatically using instructions from the smartphone. It looks for a vacant parking space, identifies its surroundings and when it finds an open parking space it begins automated parking...
Nice to have your car pick you up, but the autonomous setting I need today is:
When I am semi-hypermiling driving over 100 miles on a single charge, on that part of the trip on a two lane 55 mph speed limit highway, I spend a lot of effort watching behind me, to try to get those faster-moving vehicles that will overtake me, to be able to immediately pass me at a safe location. Nothing worse than when a vehicle slows down behind you, then goes into zombie mode, and continues to tailgate no matter how slowly (or fast) you drive, presenting a "rolling roadblock" to all other vehicles behind them.
So, after I spot a vehicle gaining on me from behind, I try to speed up or slow down to put that vehicle in just the right passing location, and at just the right speed differential (10-15 mph) so they will (almost always) make an immediate safe passing maneuver, at their own speed. Once you have a clear view behind you, you are free to (safely, without inconveniencing other drivers) minimize regen use ( to maximize efficiency) by allowing yourself some speed variable, ~42 to~50 mph in my case, on steep descents on this 55 mph speed limit highway.
Sadly, I may have a vehicle with a hypermiling-interaction-with-other-vehicle-autonomous-driving-program, before I have the fast charge locations on this highway, that would make the feature unnecessary...
