The fact is driving is the most dangerous activity most of us engage in regularly, doing it without being on top of our game at all times can and often is terminal. A good friend of mine who lives in Fountain Hill, AZ lost a granddaughter a few years back returning from a softball tourney. Her younger teenage sister was driving, the older teenage sister reclined in the passenger seat with her lap & shoulder belts in place when the driver let the wheel drop off the pavement resulting in rolling the smaller SUV. The older sister was ejected through the rear of the vehicle. I have heard a recording of the younger sister calling home to tell her family about the wreck and she could not find her sister. Talking about heart wrenching. Whoever told you that it was unsafe to recline in the passenger seat?
