I think events in cartoons should be allowed to be depicted differently to events in real life -- that's part of the nature of cartoons. If the people who make cartoons want to add seatbelts to future productions, then that's up to them, but if seatbelts are added in to existing cartoons, I don't where it would end. I hate to think of what would be done to Tom and Jerry, Road Runner or other classic cartoons.

But Pepa Pig is a cartoon AIMED AT PRESCHOOLERS. It's not exactly "Finnegan's Wake." Seatbelts and shit is exactly what these type of cartoons are supposed to be concerned with. And the studio did the alterations all voluntarily, because their job is to please the parents of preschoolers. No jackbooted stormtroopers will harm your classic cartoons.
