Some private companies offer short discovery sessions for enthusiasts, but the few I know of do cost around 150-250 euros for an hour. This particular one was within Airbus facilities, so definitely not something accessible to the general public.

It varies wildly on the simulator. Boeing or Airbus are completly able to rehost their software on a simulator mostly made from real OEM parts. From that, it's simply a matter of designing new scenarios from what you're feeding the various sensors.

On the other hand, if you're simply looking for some training hours on some specific basic scenario and/or aircraft, the simulators can be a lot rougher and still be certified. I "flew" on an airliner manufacturer designed simulator, and everything from the instrument panel to the hydraulics simulating the small impact when rolling between plates on a concrete runway felt pretty damn real.

For more basic stuff, even X-Plane exists in an FAA-approved version.

On the other hand, for the sporty versions of some midrange popular cars (Renault Mégane RS, Peugeot 308 GTi...) the pollution tax will amount to almost 50% of the MSRP. I guess car enthusiasts on a budget will be more inclined to buy lighter cars, a segment where French manufacturers are basically non-existent (even if a Twin'Cup is really fun to drive).
