You get an alert? Lets say that you are going to pass a Semi that is going 5 over. You go to pass him and as you are going beside him, you get a hit, around halfway strength(signalling that there is IO somewhere ahead.)
What would you do? Finish passing him then slow down? In front of him?
Slow down and go behind the semi?
It doesn't have to the ^^that exact situation. Lets just say you get a hit when you are passing anyone, at w/e speed.
I've always wondered :P
