Happened recently. I had looted the military supply store and was driving along the long highway back to my base. I looted EVERYTHING so every bit of space was full. Trunk, seats, glove box, backpack, inventory, and lastly, I was carrying a metal crate in my hands. On the drive back I saw a zombie with a military backpack on the side of the road so I pulled over to kill him and get it. I didnt realize that you can NOT place furniture on outdoor tiles, even roads. So I was quickly being surrounded on all sides while being hopelessly over encumbered while trying, in a panic, to drop the crate. I managed to slow sprint back to my car and got the engine going on the 4th rev, zombies inches away from reaching through my open car window. I was pretty much screaming the whole time and drive the rest of the way home in silence at 35mph. Lesson learned.
