Looked setup as he looks over the tailgate before full opening but then the final reaction suggests otherwise. must not have considered the curvature of the glass.
I have moved folk for over 40 years but always check for the like. A couple of weeks back, I moved my youngest daughter from a house to an apartment. I told her to watch the height when going into her new underground carpark. She said "it'll be right dad" Panic almost erupted as I approached the garage. I was fully aware of the lack of clearance with her 6 dining chairs on my roofrack but had to scare her for future moves in case I'm not there. Even the box trailer was stacked too high after unloading the roofrack.
