7.   Like a baby falling from the third floor and landing unharmed on a soft car roof.

8.   Or the two Dorchester girls who were mauled by a pit bull, while their mother and sister were stranded on a car roof.

9.   Startled, I glanced at this woman over the car roof.

10.   Some racks clip to the rain gutters on either side of the car roof, but not all cars have these.
