Death by floor mat, II

A few entries ago, I blogged about how a floor mat got bunched under the accelerator of a Ford truck I was driving, almost causing me to crash. Luckily, I was unhurt. Evidently, this kind of experience is not a fluke and not everyone comes out unscathed. In fact, four family members in a Toyota were recently killed in a similar incident.

Are such floormats examples of really bad (unsafe) design?
