Summary Sunny Kang has been working as a private driving instructor for 48 years. He retires on Saturday (Apr 27) when he turns 75, the age limit for private driving instructors. And their numbers will only dwindle – Singapore has only about 305 such instructors left, since it stopped issuing teaching licences in 1987.
