An even bigger conflict of interest with auto dealers is that they make most of their profit from serviceI am old enough to remember what owning a car was like when things were changing away from mechanical devices one could understand and tinker with and becoming nondescript hunks of plastic you had to buy from a manufacturer. (I'm talking about the ignition system, as one specific example.) There was always a bit of a sinking feeling for me along with a sense that the world was being dumbed down and manipulated for profit. As programmers and technical people, we should be able to see many parallels!
That said, dumbing down the world in some ways is not necessarily a bad thing and can be exceedingly positive. One might miss the twisty, dusty country road in leisure time, but curse it when it's raining and the road has turned into an impassable morass. Reliable, boring, convenient transportation is great sometimes, like when you're driving someone going into labor to the hospital.
Maintenance free electric cars that drive themselves will be one of those positive simplifying things.
