And it makes sense. If one wants a lithium ion battery to last beyond a year, it must be maintained constantly. Just ask anyone with a laptop how much capacity is left in their batteries after a year, let alone two. And Tesla's secret sauce is how they manage the batteries to last 7+ years, so that the economic equation for electric cars makes sense.

Try ignoring oil changes for a traditional engine and see what that does to the engine and -- if present -- turbo charger. It's just that the limitations are different. Ignore them at your own peril.
