Nov. 18, 2020—Toyota has filed a patent for an autonomous drone that could be dispatched to refuel, or recharge, stranded vehicles. 

According to The Drive, the drone would find cars in need of refueling via GPS, then use its other assorted sensors to make its way to the stalled vehicle. 

The patent, titled "on-the-fly," has no timeline for reaching public markets but could resurface as the popularity of autonomous vehicles increases.
