The Insurance Institute for Highway Safety (IIHS) in Arlington, Va. has just concluded testing on some 75 vehicles' head restraint systems and after performing a simulated rear-end impact of 20 MPH, only 22 of the systems received the top score of "good."

At the head of the class was Audi's A4, S4 and A6, along with the Chevy Cobalt, Ford Five Hundred (Taurus, whatever) and its Mercury counterpart, Honda's Civic, Hyundai Sonata, Jag S-Type, Kia Optima, Merc E-class, Nissan Sentra and its lesser sibling the Versa, Subaru's Impreza, Legacy and Outback, as well as Volvo's S40, S60 and S80 (no surprise).

The flunkees included the Acura TSX, BMW 5-series, Buick LaCrosse and Lucerne, Caddy CTS, DTS and STS, Chevy's Aveo, the Honda Fit and Accord, Infiniti's M35, the Jaguar X-Type, Kia Rio, Mitsubishi Galant, Pontiac's Grand Prix, plus the Toyota Avalon and Corrolla.

Considering that the IIHS estimates that the injuries sustained to the back and neck in these types of collisions costs insurance companies around $8 mbillion dollars per year, their interest in the matter is obvious. Whether or not consumers will include this in their purchasing criteria is another matter however.
