I do drive in the slow lane frequently - and this still occurs. (My go to is to set my cruise 6-9 mph over the speed limit, if passing to smoothly pass and get back over, and spend as much time as possible in the slow lane. )
However - I will say most of the roads I’m on are 2 lanes of traffic. I will have to experiment and see if this doesn’t occur when there are 3 or 4 lanes.
The idea of cruising 15km/h over the limit is absolutely crazy to me. That will get you 3 points and a minimum $500 fine here. We have "average speed zones" too!
Where I live travelling at that speed will get you passed by every cop and state trooper driving on the same road. A lot comes down to local norms and enforcement.
Apologies - you’re correct. I should have been more specific in that I was referencing the scenario of:
I’m car 2, waiting to pass car 1. (Who’s passing a car slowly ). I have safe following distance.
Car 3, passes me in the right lane, and then either follows car 1 closely, or, quickly passes them on the right. (Usually as they’re in the process of moving over, causing them to then swerve back).
I realize I communicated this in an absolutely abysmal fashion.
