Disputing the Tiger Woods air bag facts

Reports from the Tiger Woods car crash have said the air bags in Woods' Cadillac Escalade did not deploy because the car was traveling at less than 33 mph.

Somehow, I think the Florida Highway Patrol have their facts wrong. From Safercar.gov, a government resource on car safety:

Frontal air bags are generally designed to deploy in "moderate to severe" frontal or near-frontal crashes, which are defined as crashes that are equivalent to hitting a solid, fixed barrier at 8 to 14 mph or higher. (This would be equivalent to striking a parked car of similar size at about 16 to 28 mph or higher.)

Assuming the tree Woods collided with was of moderate size, I would believe he must have been traveling at speeds much less than 33 mph if the air bags did not deploy.
