Yes, I know it says that. It's a useless "fact". What highway in any place in the world would have something other than excessive speed (for conditions) as the leading cause of accidents? The only thing I can think of is landslides/avalanches in very mountainous regions, and even then I'm sure there are more than enough accidents/fatalities due to taking a corner faster than you should. I also stated that "absolute speed is not the deciding factor in road fatalities". Absolute speed is different from excessive speed for given conditions. Going 60km/hr on an unplowed, snowy, black-ice ridden road can easily be more dangerous than going 160km/hr on a dry surface with clear conditions.
