I still can't get used to the name change!
I don't know all the roads and I don't know what you want in particulier, but....
If you get the Michelin maps, the large regional versions in the 230 and 240 number series, unless they have changed them recently.
On the maps the picturesque roads are marked with a green band on the side. The best view is with the green band on your right hand side as you drive, if you understand what I mean. If the view is good in both directions there is a green band on both sides of the road.
You might want to pass by Le Mans and take in the Museum.
Furter South, just South of Brive, I like the D840 between the A20 and the A75 autoroutes.
If you take the A75, stop at the service area just North of the Millau Viaduct to get a good view of the bridge from below. It is less impressive once you are on it and not very visible from the South side.
The whole Dordogne area is a delight, but not very rapid, roughly the triangle, Brive la Gaillard, Bordeaux and Montauban.
