Dangerous to turn head all the time....there is a chance tat at the instant where u turn ur head back and u were following too closely to the car infront and the car infront zam brake....then u might knock into him....also when at junctions with pedestrian crossing....some pedestrian siao one....as long as they see zebra crossing....they assume u MUST give way to them....happen to me a few times when i turn my head to check for traffic from right....i have to jam brake.....damn these pedestrians....
Of cos you don't do Turn Head Check when u r too close the the front car ( isn't that the golden rule, not to be too close to comfort? ), your judgment while u driving plays a very important part.
Turn Head Check are good during over take and switch lane.
As for Zebra Crossing, the Pedestians r Right - you MUST give way. In China, they said - This dead Zebra will do the last say for you if anything happens when you are with him at the time of accident.
