This is why air bags are useless for people that aren't wearing a seat belt.
In this case, there would have been a very sudden stop when the car hit the bollards - there were two of them, one each side of the tree. This stop, and sudden jolt on the seat belt, would have triggered the airbag.
The driver's seat belt would have certainly prevented injury.

It's my understanding the SRS Module will activate the airbags determined by the crash sensors.
If the impact is not severe the SRS Module may only activate the seatbelt pretensioners & not the airbags.
