Personally, I have more important things to do with my time than spend it changing oil. It isn't exactly brain surgery. It's a good job for high-school drop-outs or mechanics-in-training. You macho mechanics are welcome to do the job yourselves though and I'm all in favor of your being able to.
Of course, the true solution is to get rid of that nasty gasoline engine altogether, then you won't have to change the oil at all.
The only routine maintenance required by pure EV's is changing tires (@ 25 - 50K miles) flushing fluids (brake, Power steering, and battery coolant) (@~100K miles).
