Beany asked:
I's also be interested to know where you found your data to support your statement that medical regulation does not prevent accidents or make the sky a safer place.
In France, microlight pilots have never needed a medical certificate.
Other French GA pilots always have.
There is no difference in the accident rates between these two categories. Source:

Edited to say:
Having just reread this report for the first time after a couple of years, I remember now that it covers the medical aspect only in passing, but does however make in depth the very valid point that the extremely light regulation enjoyed by microlights in France has not resulted in a degradation of the accident rate (in fact they have a more favorable outcome than the rest of GA).
However, the initial point still holds - French microlight pilots don't kill themselves or others in droves just because they don't have medicals. If that weren't the case, the DGAC would have changed the rules pretty sharpish.
