Since swappable storage batteries no longer need tools to remove, would it be possible to give custom tool requirements on different parts? Welders and hacksaws make sense for most, but not all vehicle parts. How about just needing a knife to remove seatbelts? Or a sewing kit to install them? Or a wrench and screwdriver and maybe a soldering iron to remove/install headlights instead of a hacksaw/welder? A block & tackle to install/remove engines, etc.
Same goes with repairing, instead of a charged welder to repair seats and seatbelts, maybe a charged sewing kit?
