Earth car manufacturer names make no sense
This all happened.. 'Once upon a time warp' - whatever THAT means .. so how the heck are there so many Earth references?
How can the spaceship be 'Mercedez'? (And why would it take off so vertically, when a more horizontal lift-off would be so much faster, easier, organic, reliable and require less thrust and power, etc. etc.. I guess they mimic the Never A Straight Answer nazí organization somehow, even though even they originally planned the rockets to lift off more horizontally and more gradually build up altitude)
Even the name 'Winnebago' is originally old Earth indian language, that then some corporation took as their own when they started manufacturing motor homes. On Earth.
How ON EARTH (ok, maybe this pun won't work, because they're far from Earth.. but have all these Earth names somehow anyway) can they call a spacefaring 'motor home' a 'Winnebago', when Druidia couldn't have had identical history to Earth (from the looks of things as well)?
None of these things make any sense! They should not have called it 'Winnebago', and the luxury 'car' should not have had Mercedez-Benz logo on it, and they should not have called it Mercedez, if they wanted to make sense.
I probably have to disclaim that I know it's a comedy, but they should not have put that title card about 'Once upon a time warp' in there, or it just creates confusion and things that make no sense.
Perhaps they could've had some kind of explanation, where a long time ago, some scouts visited the planet Earth and then warped in time and started naming things in Druidia and Spaceball (hard to know if this is the name of people, the planet, the city, the society, the government or what the..)
The movie, however, offers no such explanation, so these things make no sense.
