I agree with the second point, cars are a little too safe right now. I think I've had one serious accident in a car that involved lodged glass, but I don't repair windshields or windows anymore and that's prevented it from happening again. Typically the most damage I've taken is half a character's overall health, but I just eat some food and drive for awhile and everything's gravy. I also don't repair hoods, because quite frankly, I'd rather murder zombies like a battering ram with full impunity than have to worry about fixing a part that, as far as I can tell, has little to no impact on protecting the vehicle itself or the engine. If it does have an impact, it's small enough that a person can drive for hours before needing to replace a hood. The only parts that really seem necessary to keep up with are the batteries, the engine itself, and the tires. I know loot is supposed to fall out of trunks with damaged or missing trunk lids, but I've also never seen that actually happen in practice. And I'd probably be more willing to replace missing windows if zombies could bite or scratch through doors that don't have them installed (if they can already, I haven't seen it).
