Bcoz the law favouring them. Man is really suffering these kind of behaviour. Once it happned to me also. I Parked a place of a lady. I told her "I didnt see the board bcoz it is turned to the sky...nobody can read this" and "I am so sorry..if I knew never do it" I was thr with my infant(3mnths old)..and I told her "we came in emergency bcoz my baby is not well" she keep on waiting us 20minutes outside after that she took her car back from my car. It was happned in a hospital and that lady is a staff of the Hosptial.
