I really have a problem with tailgaters, like David Lynch. Not only the jerks could not avoid crashing into my car if I have to do an emergency braking but they won't make me drive any bit faster because the cruise control does not care about how close is the car behind.
I think that tailgaters lack consistency: if they do not want to respect the speed limit (which I usually exceed of 5%) then they should overtake, whether we are in town or the line is plain, because why would they bother of one regulation (passing prohibited) and not another one (speed limit).
Finally, unless tailgaters sign an agreement where they would pay the tickets I would get if I drive faster to please them... they can stick to my fender!
