I'm *this* close to placing an order for a Model S to replace my 10 year old SUV - for fuel savings and fatigue reduction on my 600 mile r/t drive between So cal and Mammoth (10-14 trips per year). But my alternative for about the same money as a loaded 85D is buying an old Cessna 182 or Cirrus SR20 to reduce my trip time in half or less - I'm a private pilot but have never owned an airplane. I figure the plane will work for at least 50% of my trips - the other 50% due to inclement weather I'll just take the SUV. Unfortunately I can't afford to buy both right now - if I get a plane the Tesla will have to wait another 2-3 years. So what are the initial reports on the effect of autopilot on your fatigue reduction on long trips? Is it significant, given that you still must monitor the systems and be ready to take over at a moment's notice? My experience with airplane autopilots is that they are a BIG reduction in fatigue vs hand flying the aircraft and leave much more of my mental bandwidth available for monitoring systems and communicating on the radios. But on the other hand in a small plane if you have a problem with your autopilot you are not a split second away from ramming into a hard object.
