That's a good summary, but a few things are still lacking. 1) A lot of people want to dump gas for socioeconomic-political reasons -- whether that combines with #1 & #5 depends on the individual. 2) The different/new/better tech of EVs (beyond Tesla) still attracts a lot of techies. 3) A *lot* of EV owners/lessees (beyond Tesla ones) love the instant torque/performance of their EVs, and that was surely a buying factor for many of them.
I recently conducted a survey of 819 EV owners/lessees. ~20% had a Tesla. When Asked about their favorite thing about their EVs, 18% chose the climate benefits, 16% not supporting the oil industry, 13% instant torque, 11% convenient home charging, 10% can drive on sunshine. Remember, though, these are early adopters. When it comes to EVs becoming mainstream, the climate benefits most certainly will not be #1, and I am confident "not supporting the oil industry" won't be in the top 3.
My 11 cents
Good point, I'm one of those who would like to see us move away from oil for socio-political reasons, as well as local pollution issues. Spilled oil and fuel gets into waterways, transporting crude by pipeline or rail can lead to spills, cars with faulty emission systems pour gunk into the air (as well as diesels) that ruin air quality. I grew up in Los Angeles when the air quality was at its worst and I had chronic allergies throughout my childhood. They went away when I moved away, but it scarred my lungs and sinuses. History shows that there are a lot more damage done by accidents transporting crude oil than there are transporting electricity over long distances.
I also agree that most of the people going for an EV now have some kind of motive like climate or socio-political and that won't hold when they become mainstream. I've noticed that the bulk of the population tend to reject any new idea until they have seen that it doesn't cause problems. Resistance to marijuana and gay marriage declined very rapidly when various states (and other countries) made moves to legalize and nothing terribly bad happened. There are still some people strongly resisting both, but the middle of the population who initially resisted now accept the idea.
These same conservative people (not necessarily politically conservative, just wary of change) need to be shown that the new thing is at least neutral to society as a whole. If it can be proven to be a benefit, all the better.
EVs, in their current form, are still a new thing and there are some legitimate arguments against them. In an ICE, I can drive from Portland to the Bay Area in one day only stopping for food, calls of nature, and short refueling breaks. It takes 10 minutes to put 400 miles of fuel in my car and deal with snacks and a potty break. With a Model S, the maximum I can get from a fill up is about 250 miles, and that takes an hour or more at a supercharger, though about 200 miles takes about 40 minutes. I don't have a Model S yet, so I don't know how that will play out in my life. I think I can probably recharge myself by taking a short nap while the car is recharging. However, it is something that requires changing the way you drive on a long trip.
High speed chargers are also still a bit spotty. There are some parts of the world where CHAdeMo and/or superchargers are common, but they still aren't ubiquitous. Gas stations are. If you're on a back road in Arkansas, you can find a gas station, but you might be only able to find a 110V outlet to charge your EV.
There are advantages to EVs over ICE, such as more compact motors, much better torque, being able to refuel the car at home, etc. But there are still some drawbacks and the charging time probably won't be solved until the battery technology changes to some new type of battery chemistry that hasn't been invented yet. Even if invented tomorrow it would be at least 10 years before they were in production cars, probably longer.
The conservative middle have to see that EVs are safer, more convenient most of the time, peppier, and generally better than ICE for almost everything before they are going to be swayed. Those who don't want to see EVs become popular are doing everything they can to convince the middle that they aren't better. Most traditional car makers who make alternative vehicles make the consumer feel you need to give something up and/or drive a car that makes you look like a prat to use those alternatives. I pretty much exhausted all the alternatives looking at cars. The bulk of hybrids take up trunk space with the batteries, so you have little cargo space left. The Fusion PHEV only has an 8 cu ft trunk. The ICE version has 16 cu ft.
The Prius is popular because it is one of the few alternative vehicles from mainstream car makers that doesn't have huge sacrifices. However, I find them kind of ugly and no Toyota car has enough legroom for me.
