It is true that deaths per million miles driven are down somewhat dramatically since the early 70's. If we had the same death rate per million miles, we would be killing about 150,000 people per year instead of only 43,000.
However, 43,000 deaths per year is an extraordinary number of deaths. Much more should be done to decrease the slaughter.
I believe that so many of us are touched by the tragic deaths of loved ones, friends, and acquaintances, that we would support a major highway traffic safety program. I good politician could find a ticket to the White House on public traffic safety.
I believe the starting place would be to eliminate high speed opposing lane roads. It could be done in a few years for a few cents per gallon in taxes.
