It's better if he hits the concrete barrier. Less paperwork for me, less lost time, and don't have to deal with the 'WTF were you doing in my lane you idgit?' idiot.
To some people a lane merge simply means "last chance to overtake."

I think the flatbed is hauling railroad ties, the wooden beam things that go under the rails, crossways, but they're dense, heavy, and kind of sticky.....so almost as good as rebar.
