Is this odd? Most cars have had several recalls, and if you have never taken your car in for recall work, you need to go look up what work was (not) done on your VIN and take care of it. Lots of cars are still out there with claymores for airbags, make sure your car isn’t among them.
Code should absolutely speak for itself. But the occasional comment is still good to explain the ‘why’ of the code when the why isn’t very obvious, often due to a niche requirement. Also any time you have to break out a hack, that needs comments up the ass, what was the bug, what URL did you find the fix at, why does this hack work, etc etc. It’s very satisfying to go back and remove those hacks after they are no longer needed, often because the underlying technology fixed the bug that had to be hacked around.
