Hmmm, these comments really woke me up! I am driving with my two kids, about 3 and 5 yrs old now, sitting ( rather playing) on the front seat without seat belt while I am being busy driving and quarelling with my wife on the rear seat. No one questioned me yet on the roads is a clear indication of no enforcement of children safety in cars.
I think once in a while police should focus on catching and punishing parents who ignore children safety meassures.
