I was taught driving in UK where I studied there for a good period of 4 years.
Though some might say its always easier to learn driving outside of Singapore but that doesn't mean a driver trained in Singapore is always a better driver than those whom obtained a license elsewhere.
Take for example, navigating and negotiating a round-about.
Singapore has removed most large round-abouts in the late 80s. But there are still some smaller ones in neighbourhood estates. Personally, I feel most younger Singaporean drivers do not know how to enter and exit round-abouts.
