Scrooge's strange vehicles

[That Duckfan]

People who have read a bunch of Italian Scrooge adventures will know that there's this moment at the beginning of every adventure where Scrooge appears at Donald's house with some strange vehicle designed for rough terrain. The unusual design of these vehicles provides a gag panel. I wouldn't think much of it (the vehicles aren't that out-of-style with the rest of the comic), were it not that this is such a staple.

Where does this come gag come from? Was it introduced in some famous story? And why does it seem to have such staying power?

I always noticed it subconsciously, but now that you say it, I know realize how it's quite the recurring pattern!

Often, it's when they go treasure hunting, and the vehicle is designed by Gyro.

Finally someone that thinks like me! I'm sure it comes from some Cimono story,it often comes from his stories. In the next posts, I will send scans of where it happens.
