Could have been much worse..... still OP, hoping your neighbour gets a thorough checkup. Concussion issues can be deceptive, and ongoing.
Should do it anyway, but if I was putting on the mega miles I used to, would definitely have good cams in the vehicle by now. A good part of that is just for self-defense, legally, IMO.
How courts work vs. how they should work.... whole thread right there. Simple example - late model Benz hits a pedestrian - it's considered routine in some geographies for the pedestrian to get sued for damage to the car.
In this twisted legal universe, I know that lawsuits have been launched (and won) by the people who caused the accident.
The # of uninsured motorists out there is staggering.... easy to see why police resources can be overwhelmed.
