The key to changing behaviour is to design and enforce policies backed up by penalties and license restrictions, the three strikes and you are out had worked for New york and heavy fines and black point systems have worked in the UK. People will adhere to laws and regulations if they know they would lose their drivers licenses or even go to jail for non adherance. This was implemented in Dubai on a wide scale and it really made a difference, people are afraid to drive over 100KM per hour because you dont just pay a penalty, but you get black points for every violation and each offense carries a weight in points, some are 4 points and some are 24 and that instant loss of your license and your car impounded for three months to a year.
