Yeah, over the years I have damaged muffler while I was driving on a very bad road. I also damaged front bumber and oil pan during the incident, so muffler wasn't my biggest problem.. not even if there was a zombie acopalypse.
I don't know if it's a thing in PZ but I would love to see sitting car condition decrease over the time. I bet that in real life you wouldn't be able to start any car that had been sitting on road over the winter - battery dies, oil degrates and gas tank collects moisture and condense.
One bug to report: You can read skill book and sleep simultaneosly in a car.
