This elaborate and expensive car commercial (via Mark Evanier) is based on the assumption that a lot of people grew up watching Wacky Races. That may well be true. You never know which country a Hanna-Barbera cartoon will be big in – the most famous example being Top Cat, an also-ran cartoon in the U.S. and Canada but one of the biggest hits ever in Mexico.
(For my part, I never saw Wacky Races as a kid but did see Laff-a-Lympics constantly, so I guess it’s more proof that TV cultural knowledge is based mostly on when and where you happened to watch TV. That’s kind of sad, I know.)
