Honestly, it might be pretty hard to get that, since it'll be about dozens of vehicles minumum, but I'll give it a try, including pictures of how large they are in mils and thus how far away they should be, and how far away they actually are.
And seriously, who would vote this down? This is a sim, not CoD. Being able to do things that are very essential IRL is what this game is about. Having vehicle sizes dodgy is up there with not having automatic weapons.
