B&S, you don't really "feel" the transition from one law to another, except the direct of course, where it is a little instable and small correction on the stick cause stronger inputs, some sort of a sporty aerobatic plane in level flight.
You only know that you changed laws by looking at the warnings and cautions you get on the ECAMs. Most of the time you come out of the sim and the instructor says "that was now alternate" and you say, uh, that's why. But you don't have a big red lamp on your dashboard where it says "ludicrous law now".
So everything is pretty much straight forward and doesn't need any special intellectual or haptic challenges. One point on the "Golden rules of Airbus flying" says "an Airbus behaves like any other aircraft", and so it is.
