This just reiterates what I think we all know: EVs make tons of sense if you have the ability to charge at home, but if you're going to be reliant on level 3 charging, or will be forced to use it frequently, it worsens that value proposition significantly. Unless the cost of level 3 charging comes down to at least parity with gas, EVs just aren't going to make sense for at least some portion of the driving public. There are some people who drive significant distances on a regular basis, and paying more to refuel isn't going to be a winning argument.
I understand that gasoline is significantly, though quietly, subsidized in the US which is definitely putting a thumb on the scale. But since I don't foresee that changing any time soon, it's a hurdle that EVs are going to have to overcome at some point, if they can.
