I get that often on 2 roads I will use leaving my town for work. Speed limit is 25MPH. I set cruise for 30MPH because these roads are a good 2 miles long going dead straight. It's also policed often and I want to avoid getting yanked for something stupid. I still get passed like this by people.
Honestly, I could see that window frame, that toolless shelving acting like a crumple zone, especially is he was already going slow enough at the time of impact..whichbit seems like he probably was, only getting windshield-deep into the building..
