At least if that was hit from the side (not saying he should have rolled out like that), even a small car probably would have broken that lumber, or had it ride over top.
I was out for a ride on my motorcycle last evening, taking a rural ridge road that goes through some great rolling countryside past a couple of towns west of here.
There is one intersection that has a 2 way stop, for the north/south road. Visibility is good, as it is where 2 rolling hills meet. Last year, I had to slow down quickly on the right-of-way east/west road, for a "gentleman" in an E450 blowing through the stop sign at about 20mph.
He had about 15' of a two and a half foot diameter log sticking out the back of the rolled up van door. Even in a pickup truck, hitting that from the side at 50mph would really mess up your day.
Every time I ride along that ridge line, I use that memory to remind myself that you can't be too paranoid out there, regardless of what you are driving.....
Plenty of the these posted pics would have our green-bears in Ontario writing so many tickets that they'd take a month off and need physio to deal with the writer's cramp !
