Put away all tools and click on the vehicle to 'push' them slightly. If you do this enough, then most vehicles will be able to right themselves. (They have a slight righting force already, it's just overpowered if you flip the entire thing upside down)

Space, can you make a vehicle grabber?And doesn't the gravity gun only lift the companion cubes?
