I think it's a pain in the ass to always have to add people to your buddies to let them sit in your car. Especially when your a cop, and you need to get them to the nexus fast. I think to make it more realistic/a lot easier, cars should automatically let people sit in them. I know that the buddy system is there so unwanted people don't get in your car, but I think, if anything, an easier, more efficient way to let people sit in your car should be added.
