It is indeed part of things I have to add, but the list is very long

Being able to see vehicles only in America movies, or being able to see vehicles only in Italian movies. Etc etc etc

I'm not sure to understand what is your request here
Do you mean having the filming location of movies? Or something else?

Maybe so that for vehicles that weren't listed with their proper country of origin (*cough cough buses cough cough*) it would be somewhat easier to ID them then go through the huge swarm of vast pages.

Someone probably has already suggested this before but I figured it's worth asking
