What I notice in Australia is when police want to pull someone over will often follow behind a car with their lights turned off until there is a safe area to pull over - then will turn on their lights. This might be a few minutes down the road. Some people will immediately see lights flashing and pull over straight away without checking for a safe location, so by delaying their lights - it removes that out of the equation.
