I know car cheats and mods and alterations have made them invulnerable to damage, but glass still breaks, which really pisses me off. I like taking my car out for a spin and killing some aliens, but I hate when the glass breaks. It makes the car look like shit, especially when all the other windows are black or another dark color, and there's no windshield. Even if by making the glass unbreakable, it would change all other glass (I.e. rim jobs side window), it would be very worth it.
