Its too bad PHEVs are not modular to allow for removing the gasoline engine for the 90% of trips where you don't need it.

In fact, I have a vision for modular PHEVs where the gasoline engine is on a trailer you pull on trips, and all it does is charge the electric battery to keep the electric motor running. You wouldn't even have to own or maintain the gas engine, you could rent them at u-haul or some a car rental chain.

I would actually love something like this for my Tesla.

They had a range extension trailer for the original Tesla roadster. I don't know how popular it was...

The main issue with that is the total efficiency isn't that great.

If you're not taking frequent long trips, than it seems a pure EV makes the most sense. You can just rent a car for the longer trips.

If you are more frequently taking long trips, but your daily trips are often short enough, a PHEV can make the most sense.
