I was driving on a rural road (about 40-45 mph) and missed a stop sign at a t intersection, went straight ahead and struck a guide wire, a large bush, then a block wall, and came to a stop after passing through the wall and entering the building. the car never veered but went straight as it struck these structures. air bag did not deploy and i sustained a broken rib and injury to the chest wall. emergency personnel could not explain why the airbag did not deploy. the car was inspected and found to be a total loss.
