Fair point but we're heading to rural france so hoping to find some quite stretches of country road.

Yeah be careful over there, they do not take kindly to speeding foreigners. I drove all the way to the Swiss border with my cruise set to 85 all the way. (about 80 on a gun)... Police were hiding everywhere!.... Mind you I did get a chance to have a bit of fun once up in the mountains!

Heard some horror stories though, for example: a guy was caught speeding so they took his car, he had to fly home and then go back 2 weeks later to get his car back!...
I found the French Autoroute's a pleasure to drive on even though there are only 2 lanes.. 99.9 % of all drivers kept to the right unless overtaking and always returned to the inside lane, it was great!
