Car rolled and airbags did not deploy.

I was in a motor vehicle accident. I lost control on a sandy road, had a tank slapper at 30 kph and went into a ditch. The ditch threw the over and I rolled.

I’m disappointed because the car’s airbags did not deploy. By God’s grace I was not injured but as a BMW fanatic and as someone who’s family loves BMW(we currently have 4 in the drive way and have had others before) I’m questioning if I should get another one.
