You can just fill a can with gas and bring it to the car.
(this is what a tow service will do if you've only run out of gas)

You're right of course, although I still maintain plugging the car into a wall socket for an hour is easy to do almost anywhere - realistically this would get enough charge for most people to get to a charger (in my case it would get me to a rapid which would top up the rest of the battery in another 25 minutes).
A 1kWh battery is not big; e-bicycles carry ~500Wh.
Would be literally the electric equivalent of a gas can.
