Alain Prost and Ayrton Senna were vicious competitors on the track, never afraid to do whatever it took to outperform the other. It turns out that competitive spirit extended to the commercial side as well, though when it comes to this ad, it looks like a competition over weirdness.
In case you're forgetting, Ayrton Senna wasn't above shilling for his sponsors every now and then. As a Formula One driver, it's really par for the course. The thing is, though, that F1 drivers have fans (and thus, cold hard cash) coming in from all over the world. There's nothing really wrong with that, except for the fact that people all over the world tend to speak different languages. So when you get a guy like Ayrton Senna, who doesn't speak Japanese, and you need him to sell some engine lubricants you've manufactured out of dead dinosaurs, what do you do?
