Just come back from a quick trip to France to see the in-laws and I always knew there was a difference between motorways, but I never noticed it as much as today!!
We drove about 3 hours in France and Greg was doing 130 / 140 kmh which was fine and nice and smooth....
Then we crossed over and had to drive for 1.5 hours to get back home and I hated every minute of if!

As soon as he was trying to get slightly over 70mph I thought everything was rattling, the road noise was bad, ride was bumpy...
Anyone ever noticed that too?
