Well, the issue with road tax is easy- they can just take a odometer reading at the annual safety inspection (for States without an inspection, that might be annoying, although there aren't many- Alaska, Arkansas, Iowa, Minnesota, Montana, South Carolina, South Dakota, and Texas, and a few others with complexity). I see hybrids as the "worst of both worlds" type of situation. All the complexity, expense, maintenance, and strangeness/quirks of two drive systems, so I have never been interested in them. Plus, in my situation, I just don't drive enough to justify it.
For those of us who don't drive a lot and rarely take 100+ mile trips, the charger situation is kinda moot, as long as one has a way to charge at home. And that will be a big problem for people who live with on-street or lot parking. Of course there are more and more charging stations, but that won't be convenient like a gas station where you are "filled" and gone in just 3 min.
We definitely should be oil self-sufficient in the USA. This idea that suddenly EV's can replace gas in even a few DECADES is insane.
