NUTS
[…]
But if there's one thing I remember about Sim by, it's his criticism of the Singaporean mindset.
The No U-Turn Syndrome, or NUTS, was how Sim viewed how Singaporeans always required a rule base to get anything done.
It's referring to how in Singapore, u-turns are not allowed unless there's a sign that allows you to do so, which is different from how other countries do it — you can u-turn unless there's a sign prohibiting you to do so. And to make things even more fun, there are sometimes no u-turn signs, too.
