I remember back when Vice City was going to come out I posted in a wishlist "The ability to fill up your gastank".
The responses where awesome.
"That's just plain stupid."
"We don't want that kind of realism."
"That'd be the most annoying feature EVER."

Besides. This is gta who would ever get out of gas? You switch cars as fast in gta as you switch girls when you're 14
