I feel like you missed the point. The point is that you probably want to stop every few hours anyway so there's not a lot of point getting a PHEV. You're buying two engines for the price of two, with the maintenance costs of a gas engine (higher) and extra weight. It's just fear that gets people to buy PHEV. There's hardly any mpg benefit over a gas car in real world usage, and there's hardly any of the lively acceleration of a proper EV. No fun, no cost savings, just all initial expense. Get an EV or stick with your old gas car, PHEV is absolutely not the best of both.
