News-Medical.net posted an overview of a University of Rochester study which found that side-impact crashes are three times more likely to produce a traumatic brain injury than a head-on crash. I believe that as more studies looking at brain injuries and auto accidents are conducted, the results will force the auto industry to equip more automobiles with side-impact air bags. There are some vehicles on the market that do have side-impact air bags, but many only have frontal air bags.
