I hope they can compete with plugin hybrids. We have a BMW X5 plugin hybrid, bought on the advice of a friend, and it's such a great car. Almost always on electric in town, and for the rare times we go on road trips we never have to worry about range anxiety.
I really feel that plugin hybrids with 40-50 miles of electric range are the ideal car for like 85%+ of Americans whose usual daily commute could all be done on electric. I've heard all the arguments against them, and after owning 2 PHEVs (Chevy Volt before this), I disagree with all these arguments. Yes, I understand that they're more complicated that a pure EV, I know pure EVs will be the future (I'll also be dead in the future), but my ownership experience with PHEVs over the past decade proved they were the perfect car for me. Never had any reliability issues, and despite hearing arguments that they are "the worst of both worlds", they were definitely the best of both worlds for me - all the benefits of an EV (low operating cost, fantastic acceleration, quiet, smooth ride, almost no trips to the gas station) with none of the downsides (didn't need to install an expensive charger at home as the wall charger was sufficient, never had to worry about range anxiety, never had to carefully plan road trips around charger locations).
I think you're directionally correct. But that BMW will likely turn into a maintenance nightmare in 10 years when electronics modules start failing and new replacement parts are no longer available. Might be best to lease it instead of buying for those who can afford that option.
