"An even bigger conflict of interest with auto dealers is that they make most of their profit from service, but electric cars require much less service than gasoline cars. There are no oil, spark plug or fuel filter changes, no tune-ups and no smog checks needed for an electric car."

Well then what about BMW with bumper to bumper service as only one example. That's a high end car that you don't pay for service for (iirc) 3 years. They cover everything. Wiper blades you name it. I think last I checked the same was true for Subaru and I think even Jeep Chrysler is doing this (may be wrong about that one).

And that's not a conflict of interest but rather a business model. In the case of cars which do make money from service they therefore in theory have a lower price for the vehicle.

This argument is like saying that you are a better airline because you don't charge for luggage. Presumably that extra revenue allows you to offer lower ticket prices. And surprise that is what happens. Back when airlines were regulated (and had less competition) and they charged way higher prices they didn't have to nickle and dime you to make a profit.
