You need to balance it against the amount of disutility from deaths caused by the line going at speed+5 on a road where they were supposed to be going at speed. You need to also add the disutility generated by that line fucking up traffic flow in the nearby area.<p>Seriously, this stuff is to be determined from top down, not from perspective of individual self-interested drivers with zero context, little responsiblity and no interest of ensuring optimum flow.<p>Also, the general culture of aggression and disregard for law is something that is not healthy for neither society, nor economy.
