Oh, I certainly don't: there's a permanent speed trap there.
It's conceivable that there's a reason for it. The road as a whole should be a major arterial, but it's got an awful lot of stop lights. (This is just outside of Washington, DC, which has practically no proper arterials.) At rush hour, allowing people to go faster on this section than the overall speed of the road would be worse for traffic.
What's really needed is to substantially restrict access to that road and make it a highway, though I'm sure that the businesses and residences along that road would hate it. The problem is systemic: there are no arteries and nobody wants to turn their stretch of road into one. There are zero interstates, so the roads are under a variety of local jurisdictions. I'm sure plenty of people complained to the county and state about that segment of road, but it's just a disaster for the whole region to deal with. And so it isn't.
Er, anyway, that's kinda beside the point, which is really that what's needed is for the traffic engineers to design for steady flow and for people to follow it, even if they'd be more comfortable at some other speed, especially when lanes are limited. But it's easier said than done in a metropolitan area.
