How do EVs have “engine failures?”
The Flintstones’ and Rubbles’ cars were not automobiles because they were foot-powered. EV’s are automobiles with batteries and motors (engines). Gasoline and Diesel-powered engines are also features of an automobile’s drive train. Something has to develop enough torque to make the transmission do what it’s designed to do, and if your talking about automobiles, it doesn’t include your feet.
Motor are not engines (in the strictest sense).
