I think we should more than GTA IV, as I don't want to spend ages driving to a safehouse to save my game. Also, even in TBoGT, I felt that there wasn't enough places to save the vehicles I wanted. Yes SA had a lot of safehouses, but quite a lot of them didn't have garages to store my cars. I think there should be extra places for you to save your cars, such as parking lots or garages that aren't attached to a safehouse.
