And you gotta keep up with the general flow of traffic, especially on highways. If everyone is flying by at 80 MPH you should probably follow suit. Hanging out in the slow lane doing 60 because you're "too cautious" or worried about speeding can just cause more harm. Other cars will just fly past you, change lanes to go around you, and it could end up causing a problem.
If people want to drive stupidly, it is their fault, not mine.
