That is, until the point where the wheelchair user got halfway across and saw a car heading towards him wasn't slowing down and this would have forced the wheelchair user to be stuck in the middle of the road to wait for the traffic to die down. Seeing he'd be a sitting duck, Mr. Wheelchair user wasn't having any of this, so he turned the wheelchair and began to ride down the hill in the road at a slow pace, with the car (and subsequent traffic behind it) following slowly behind, hitting their car horns in anger at the wheelchair user, who was also told to "quit hogging the road."
I have no idea what to make of that, though.
