I looked into this a few weeks ago while exploring purchasing an electric car, and from what I could find "tow charging" was experimented with but has basically been given up on. The expectation is that if you lose power, you will need a flatbed truck to cart the car to a charging station.
> Charging efficiency isn't 100%, so you'd have to tow it further than the range you need
That's not how it works. You basically get 5 mpg or less on the truck, while the car charges at significantly higher rates than the speed of the truck (in mph), because the car is more efficient at using the energy.

Towing at 70mph in the above example was charging the car at 65 kW. That's equivalent to ~260-270 mi/hr of charging rate assuming 250Wh/mi.
