That’s not what he’s describing. They build a road that’s saft to drive at 30 and then set the speed limit to 15. It’s an invitation to “speed”. And what’s worse it makes the road more dangerous.

It’s an invitation to “speed”.

Even in such a situation, it is almost always the driver's fault if he or she speeds. I routinely drive fast on roads where the posted speed limit is 30mph but could easily allow for faster speeds. I haven't been ticketed, but if I am, it doesn't matter what the design speed of the road is.

The times when a cop does tail me, I just set the cruise control to 30mph and watch as the "parade" backs down behind me.

I have driven that same stretch of road many times. The writer failed to mention how many blind driveways there are as you twist and turn your way down the hill. 30 mph would make it almost impossible for these people to pull out onto the North Glebe without causing an accident or getting killed. If he wants to drive fast down big hills, he should drive out to the Blue Ridge Mountains or go even further to West Virginia.

From the article: "It turns out that the speed signs do perform an important safety function: in wet weather, many drivers had taken the curve too fast; traffic authorities have substantially reduced accidents on the curve by adding the 15-mph warning sign..."
