What (light) injuries should be expected after car crashed in a brick
wall at approx 60 m/h if the driver wears his seatbelt and the airbags
do their job ? (the car is a BMW 325 2004) Thanks

That is a bit of an ambiguous question, there is a hundred different
variables besides the speed and model of the vehicle. The thickness of
the brick wall, the build of the wall, the pre-tensioning strength of
the seatbelts, condition of the car in the first place, mind and
reflexes of the driver, bla bla bla.

I'd suspect light head injuries, whiplash, medial upper skeleton
fractures, bruising to the body and ego LOL
