I just got bitten whilst driving in my car. There were a group of zombies on my left hand side, and I was driving into the bottom right corner of the screen (i.e. I couldn't see the condition of the window the zombies were banging on). I heard the bite noise, then saw I got bitten twice.
I assumed that the car window must have broken without me realising and they bit me through it. However, when I drove off and checked, not only is the window not broken it doesn't even show any damage. I checked the window condition via the vehicle menu and it is not broken.
How did I get bit? Is this some sort of weird feature where zombies can now bite you through partially broken windows? I can't imagine it would be as only the windshield is really that damaged and all the zombies were on the left hand side. See the pictures.
I have no mods installed, but feel like I'm within my rights to install a cheatmenu and save my char? Bit disappointed, really.
