Obviously tripping. The answer is in "keep left, pass right" regardless of speed. In RSA we drive cars on the right hand side, meaning we overtake on the right hand side. Overtaking on the left is dangerous as one doesn't have a clear view of the road and any obstructions ahead.
But expecting people to move out of the way cos you’re speeding is crazy entitlement. If I’m driving at 120km but you want to drive faster, you should change lanes and overtake since you’re in a rush and want to break all the rules. Or am I tripping?
