sometimes you do need to hotwire a car because it don’t have keys, it usually shows up as a prompt when I go to take control of the car for the first time and if I manage to hotwire then the alarm goes of and sometimes if your unlucky disabling the alarm you can break the controls. as for the screwdriver issue, I’m not sure as I never seen it.
Edit: FYI, I Never noticed condition of controls, maybe better condition ones have keys while lower condition ones don’t, as far as I know it’s a random chance to happen.
