   actually it didn't make much of a difference.   
      
   when the nmsl was imposed, people started driving a lot less because   
   gas prices were climbing, which means people drove less, which means   
   the raw number of fatalities went down.   
      
   also, people routinely ignored it anyway.   
      
   when the nmsl was lifted, the number of fatalities continued to   
   decrease. also the average speed of traffic went up only by a couple of   
   mph. in other words, people had been ignoring it for years.

   radar & lidar based blind spot assist and adaptive cruise control come   
   to mind.
