Yes, I'm finding same in France at present. Not being used to their off ramps they do seem to have some very tight turns just as you exit motorway onto ramp. Suddenly have to lose a lot of speed quite quickly. Have to be careful as my van isn't exactly designed for tyre screeching cornering. Almost caught me out couple of times.
As for German autobahns, the most stressful motorway driving I've ever done. Most I drove on were only dual carriageways - slow lorries in right, warp factor nine turbo-nutters in Merc/BM/Audi in left lane. I was neither one nor other of these two classes of traffic, so spent most of the time, playing Frogger - constantly scanning my rear view to see if I had a brief chance to move to left lane to overtake a slow lorry before Mario Andretti suddenly apperared on my bumper filling my mirror. If you do get it wong after moving out and someone appears from nowhere at speed of light on your tail, they will sit there 12 inches from rear bumper as you overtake trying to almost push you to go faster.
Absolute nutters and saw the very nasty results of when all this speed goes very wrong over there - in the massive traffic jams, dozen emergency vehicles and piles of mangled wreckage. Absolute insanity and very stressful to drive on. Most sane motorways I've driven on were US freeways. Big roads, plenty of space and low speeds. Just put the Buick in cruise control an nod off.
