Stuck in a car

Alix Paultre, Editorial Director, PSD

Almost all of us have spent a large amount of their lives in a car. From being ferried from the hospital at both, to school as a child, or to work (and if you are lucky, vacation) as an adult. (You could say that the car made moot the riddle of the Sphinx.) People have been conceived, born, and died in cars si
