Is there anywhere that lists the peages locations so you can put them into a GPS? If they're in lat and long format it'll make it a bit easier I think. Really only the ones on the main road, as even I can guess where they'll be on the exit slip roads. Autoroute 2003 is quite a long way out BTW.
I've read that the gendarmes are getting quite hot an a common ploy is to zap you on a bridge some distance before a peage where obviously you have to stop and where there have been no convenient exits
Now normally I'd not be going that fast or be non observant, but it would help getting the money / card ready if you have a countdown to them. Plus as time will be short next year most of northern France will be at high speed and having them in as waypoints will help keep Betty on the staight and narrow.
