4. Lock Our Car Doors
Getting out of your vehicle and rushing to the nearest Sprunk vending machine is all well and good if you are playing GTA, but spoiling this experience would definitely be first and foremost having to lock up. An animation for getting the keys out of your pocket (for older cars of course) or the annoying sound for area sensitive locks would drive you insane. One positive advantage though is the less likely chance of your car being stolen by common larrikins, such as you are, dont deny it we all steal the closest vehicle when times are tough.
