I have a 2018 Clarity and know a few other people who own PHEVs. I don't know any PHEV owner who doesn't plug in, and the GM CEO's comment is very misleading. Driving daily around town, I'm currently on 452 miles without using any significant amount of gas. Charging is done using solar panels on my garage roof. Buying a PHEV was one of the best vehicle decisions I've made in my 65+ years. I understand the technology required by PHEVs is complex -- as one engineer friend of mine told me, "PHEVs are the most complex car that has ever been built, and ever WILL be built" -- because purely electric cars are so much simpler. The Big Brands don't make the same kind of money with PHEVs that they do with pickups, for example, so they don't want to make them. But honestly, homeowners would love them if they could all get 40-50 miles/per charge like the Clarity, because most people don't drive their cars over 45 miles/per day.
