Sundays are fun around here. There are a few shopping center areas where cars gather for show, and these become meeting places for a caravan up to the next show. The Church of the holy Donut is the largest nearby show, and afterward the guys like to romp with the cars. I think the roads through upper Montgomery County Maryland were designed by a frustrated road course designer.
With 5 Million Americans living in Maryland (one of the smaller to normal sized states), upper Montgomery County has many backroads similar to a never-ending road course (two lanes divided, so only one lane for driving). Passing is rare since they wind up, down, and side to side through tree-lined roads. So, driving at speed is fun, too. Many times there is no way to see over the top of the approaching hill or around the corner, so you have to scout the advanced area from a high point before approaching it at high speed. For the brave, tires leave the ground and cars come down to find an angle of driving different from the landing. This can go on for hours with little to no traffic, and steering gets full use of the wheel around many of the fun corners. I'll admit that getting behind a couple of "slower than 30 mph vehicles with no sign of passing available" can feel like an eternity. The 4 lane roads are just outside of these roads, and just outside of them is the 4 to 6-lane (each direction) highway I-270.
Unfortunately, Speed Cameras are popping up in the oddest areas now. They used to just be near schools, but now are found in areas where the speed limit is ridiculously slow and no one is around (IMHO).
There aren't any traffic cameras on the backroads (because there are no lights), but if you click on the link below and scroll up toward the upper right, you'll see Burtonsville, Maryland (Rts 198 and 32). A google search could give you an idea of what the roads look like from above. http://www.trafficland.com/city/WAS/index.html
I know England has great roads (when the weather cooperates), too.
