yeah i used tos ee this alot working in childcare... there ws one particular family who had two very boisterous twin boys 3yo as well as a 4yo disabled boy and they just chucked em in the back of the car and closed the door.. ud always see em hanging out the window or jumoing around in the back seat its awful and i can't understand why parents would be so negligent.. we tried to talk to them on the dangers of there actions but they never listened to us...
