You know it’s time to stop driving when…

Police in Philadelphia want to speak with an elderly woman who took her Buick Century station wagon the wrong way down Interstate 95 Thursday at 50mph, causing four separate accidents. Here’s amazing video of it actually happening.

A driver on the proper southbound side of I-95 managed to film the woman, saying at one point she tried to waive him off and scuffed the concrete barricades with her faux wood paneling twice without stopping. No one was injured in the other accidents.
