Go HERE for the full analysis, but I was intrigued by the year 1974. Why the big drop-off from 1973? (I marked 1973 with the RED arrow as the high watermark for traffic fatalities).

If you look at the periods of recession in this graph and line them up with the graph of fatalities above you will notice there is is dip in miles driven and traffic fatalities. The only exception is the recession in 2001-02. Miles driven did not skip a beat.
The one I marked with arrow is the result of the Arab oil embargo that increased gas prices significantly and price controls made scarcity a problem (I remember those days as a teenager). People were very careful in their consumption of fuel and (1) made fewer trips and (2) voluntarily slowed down on the highways to conserve even more.
I don't think this explains all of the long term trend in decreased traffic fatalities. There has to be more, right?
What do you think could be a contributing factor?
In terms of recent times, what correlation can you make with the leveling off of miles driven during and post-Great recession and the rapid decrease in traffic fatalities? The recession is over so it should be trending up, right?
So many questions! Do you have answers?
