This may not have much relevance to jiwawa's question but could I post my thoughts on 'Normal' roads versus Toll roads ?
Just a personal view on French Toll Motorways and 'normal' French road.
We use the Toll roads at the start and end of the holiday to get us further into France at speed and our early destinations and we don't mind paying the price for the time it saves against using 'normal' roads.
And then we meander around from Motorhome Aire to Aire on normal roads for much of the holiday
But normal roads - many very good and relatively traffic free - in my opinion can be a pain in the butt.
There seem to be Villages every few miles with their chicanes, speed bumps slow you down to around 20 mph and rattle everything in your vehicle and its chassis and many 'Passages' (pedestrian crossings marked by white 'blocks' across the road) in each village and town that have to be keenly watched.
Stopping for pedestrians on Passages is considered mandatory and watching out for pedestrians who suddenly walk across without prior warning can be an art in itself.
Town ring roads usually have many roundabouts, constantly slowing down and speeding up, every few hundred yards and if you have to go near Centre Ville you meet slow moving traffic, long delays at traffic lights and parked traffic difficult to manoeuvre around in the narrower roads with a Motorhome and/or Caravan.
Cities have a multitude of roundabouts and traffic lights, signs that point in your direction - and then aren't available or visible when you really, really need them at T-junctions.
And don't get me started on Cyclists (as many as 50 at a time) out for a ride who are almost impossible to pass as they serenely block your path.
'Route Barrée' signs that can send you literally miles out of your way on unfamiliar narrow roads that your SatNav would tell you to avoid – but it's very difficult to avoid them when following the 'Déviation' signs.
The new top speed of 50 mph (80 km/h) on rural roads in France on a straight, flat and traffic free road can be as boring as is possible and we often yearn for a bit of welly on the pedal - which is possible on the Motorways.
Yes, France has a lot of places to see when off the Motorways - but after the 30th or 40th roundabout and 20th speed bump, constant speed changes from 80 to 70 to 50 to 30 and back again it gets a bit tiresome and irritating when you feel you could be much further on and less tired by using a few miles of Motorway – albeit at a cost.
Using Motorways constantly makes no financial sense but those who believe that normal roads are the ideal solution must have more patience than I have.
Having said all that – driving in France is considerably more pleasurable than driving in the UK.
