My vehicle was moving at 30 mph when a car suddenly crossed the path causing to hit the other vehicle on the passenger side. the incident caused some visible frontal body damage and trip to hospital with son (seated at back seat during accident). the airbag did not deploy but thankfully seatbelts did the job. i was in the assumption that airbags were made to deploy during these kind of accidents. was the impact not strong enough or defective airbag? *tr
