> One is that its uncomfortable for people in the car, particularly passenger, who are pushed sideways into the seat-bolsters and side panels. Body roll is going the wrong way to make it more comfortable. The roll is in the same direction that the passengers are being pulled, which makes the passenger impact worse as gravity adds to the pull as the car tilts. Contrast with a banked curve, which is essentially reverse roll, and is more comfortable because much of the force is directed "downward" into the seat.
