Driving in France is beautiful! The constant toll stops got on my nerves at anything between about €2 to €20 but the roads are immaculate. Next time I'm over, later this year, you can buy me a drink.
Several years ago my first wife and I drove all the way from Calais to Provence (over two days) avoiding all the toll motorways (because we're tight-fisted Yorkshire people). Despite that, the roads were wonderful; a real joy to drive on.
