That is interesting but seems like it would be impractical from a business perspective. Unless I misunderstand the translation, it could only charge one, maybe two vehicles, enough to (hopefully) make it to a charging station.

A regular tow truck/wrecker can carry 20 gallons of gas in just 2-4 containers to provide 10 cars 2 gallons each, probably good for 50-60 miles in most vehicles.
