Apparently all the engineering is paying off in the lowest auto fatality rates since the 1950's.

On Friday, the U.S. Department of Transportation estimated that 32,788 people were killed on U.S. roads in 2010, a 3 percent drop from 2009 and the fewest traffic deaths since 1949.

That year, Harry Truman was in the White House and 30,000 people died in auto crashes, even though the number of drivers was much less than it is today.
