I wonder how many EV drivers end up in the dealership only once a year.
In any case, there are always going to be advantages and disadvantages, and the market will tell where people's priorities lie. After all, there already is the $100k Model S, with its abysmal range when driving at 100 mph -- and some say that it even has too big a battery for an affordable EV! A hybrid suffers none of that with its more complicated ICE. (They're not that bad, but I'm not going to start arguing about that. I don't even know if you own one to maintain.)
Yes - absolutely. If you are a legacy car maker. You get all the benefits of the halo of "modern" technology and "green" initiative but you still get to hang on to your very lucrative ICE maintenance business (oil changes, fluids, complicated mechanicals, etc.).
As a consumer ? You get none of the technological benefits (dramatically lowered center of gravity from "skateboard" designs and all wheel drive coming from multiple motors, to name just two ...) but you get all of the logistical and aesthetic penalties that come from running a shitty little lawnmower engine inside your fancy new car.
I think the BMW i8 is a perfect emblem for this kind of flawed thinking. A beautiful, modern (looking) "luxury" car that has a 3 cylinder ICE hidden inside.
If I could say one thing to all of the legacy car manufacturers pinning their strategy on hybrids: Don't piss on my head and tell me it's raining gold.
The complicated mechanical are a negative for the most part. They have to spend massive sums of money to keep meeting the latest emissions standards, along with more money on efficiency. The only silver lining in this is the side effect that it costs so much you won't see more competition as only a few companies can afford to design an engine.
The typically model is you take the car to the dealer while it is under warranty and then go to a cheaper shop afterwards. Which means that the dealer gets some maintenance revenue (enough that as you say they are sales floors subsidized by the maintenance shop).
