Does anyone know on average how many hours per week the average person spends in the car carting their children?
Many. Especially when they start playng regional sports.
My guess is that it will vary widely depending on where the person lives, the age of each child/children, and how many children are involved. For somone in NYC it may be zero, for someone in the midwest with 4 children between the ages of 8 and 16 it may be way, way too many hours.
