SERIES PREMIERE: This limited-series Top Gear spinoff stars James May, the king grouch among this show’s pack of affable automotive grouches, to evaluate a series of Cars of the People – economical “autos for the masses,” complete with some quick history lessons to explain, for example, why the VW bug originally was referred to as “Hitler’s car.” Dictators, it turns out, have a lot to do with automotive history, though they can’t dictate what does, and doesn’t, ultimately become popular.
