I've just been looking at our map - which is actually dated 2003 - but rural roads haven't changed that much, and there are probably even more by-passes now then there were then. Perhaps one of the most useful sections is the alternatives to the Rhone valley route. You go off at Vienne, on to the D538 which continues through Beaurepaire, Romans-sur-Isere, Chabeuil, Crest, then the D9 to Grignan, and eventually to Carpentras. We've followed the section to Chabeuil when we stayed at a site near there. The alternative is to cross the Rhone near Vienne and carry on down the west side of the Rhone (useful if you're going to the Ardeche/Gard areas of France).
The Bis maps don't offer an alternative to every single autoroute, but having used some of their suggestions you get used to following the 'ruler' principle (ie look for the straightest roads, in the same direction as the autoroute you want to follow - and then highlight that route - and ask if anyone's done it before - or be intrepid and just go for it).
We haven't yet made any real errors of judgement - though we did once get lost going around Aix on Provence, and ended up having to go through the small village at the top of a hill. The worst thing was that another van was following us, as we looked so confident that we knew what we were doing!
If you've a particular destination in mind (in France by the way, Bis only applies there) then I'll have a look at my map and see what the suggestions are.
