Toyota Patent Shows Self-Driving Drone Tankers for Car-to-Car Recharging and Refueling

The patent claims this sort of system could find use in autonomous vehicles, although it doesn't say it couldn't work for regular vehicles. I find the idea of one vehicle helping another vehicle rather nice. At least, I'm assuming they would be friends. It reminds me of the forklift pit-stop character Guido, from the movie Cars. I think the whole interaction would have that vibe.
