What's the rule with doing 40 in a 40. And then someone goes for the overtake as you cross the nsl line?
I'm within my right to speed up, as it's gone from 40 to a 60 right?
Obviously if you speed up where the limit increases that is not what we are talking about here. If you had been driving 40 for the last 3 miles on a nsl road and then speed up just because the person stuck behind you is overtaking then you would be a **** trying to compensate for other inadequacies such as a small penis
