Plead ignorance… and if you drive in South Africa then I’m sure you’ve come across this more than once.
This is probably the easiest way to get away with roadhogging.
And its amazingly simple- what it boils down to, is simply not looking at the person you just hogged. This is achieved by pretending you have a blind spot the size of a basketball in ALL your mirrors at the same time.
NB: An advanced technique is combining this with lesson #4- the wave- if you do happen to glance at the person and accidentally catch their eye.
