Highway? Really? I thought the drivers set the speed limit? Do you often see people driving 100mph on RCP? Why are you defending this person who killed three people by smashing into them head on at an excessive rate of speed? |
What if we had speed humps every 50 feet? |
It's the 85% speed limit method - 85% of drivers driving at or below that speed. And, of course, 15% of drivers are driving faster than that speed. One does not often see people driving 100 mph on Rock Creek Parkway, but this was unfortunately not a unique occurrence. The 85% speed limit method is inappropriate for setting speed limits in areas with people, like DC, but engineers use it anyway. |
