Inherent safety design of the trunk lid: I got a gash in my forehead as I was opening the trunk lid and the lower edge of the license plate cut into my scalp just below the hair line. I believe that the trunk lid dropped as I leaned into the trunk to retrieve my belongings from the trunk. I bled profusely.
