1.- You can access the Copilot seat directly from the Pilot door, and viceversa, playing a very weird animation that makes your character go through the car.
2.- If you enter a car from the Copilot seat, and move to the Pilot seat, the character's hands are misaligned with the steering wheel
3.- In the ST#52 changelog, it said "visual hiding of items in hands in cars", but you can still add items to your hands slot, being them all visible.
