Only if any of those passing cars are gas-powered. If the passing cars are themselves also EVs, then there's both more obvious forms of energy transfer, but also you'll be taking that much range (and more) from the EV doing the towing.

- elihu 5y agoTransferring energy from one car to the other isn't quite that straightforward, even though it's something that sounds like it ought to be easy. (The simplest thing would be jumper cables, but there's not usually any easily-accessible high voltage terminals, and the batteries might be different voltages anyways. And you'd want to limit curren, and so on....) Maybe if the new Ford F150's 220-volt outlet becomes a common feature, then charging from one car to anther will be easier (though very slow). I think the main towing advantage a typical ICE car would have over an EV with extra battery capacity is the ability to shift into 1st or 2nd gear. It's not really an intrinsic property of EVs that they can't have transmissions, but so far the major manufacturers have decided it's not worth it. (The Taycan is a notable exception.)
