Though the H2 is engineered to prevent rollovers they aren't bullet proof.
My dearest friend's son was traveling about 65 mph on a large overpass in Houston around 2:30 am last Saturday morning when his '06 H2 was struck in the left rear tire area by a drunk driver that was approaching from behind at a high rate of speed. It was basically a classic take out maneuver.
The H2 began to shift the rear end to the right as he attempted to correct it by turning into the spin his H2 went airborn & flipped/rolled onto the drivers side skidding another 100 yards into the guardrail. He was looking out the sun roof off the edge of the overpass at a 50 ft drop.
He survived but now has a possible life changing injury from a torn rotor cuff. (He's a college student on baseball scholarship as a pitcher.)
No air bags deployed which has me wondering what it takes or if they failed in some way.
Does anyone know what triggers them or when the air bags should deploy?
