The flight of that Rallye under the Arc de Triomphe was described in detail by Bernard Chabbert in Pilot. Alas, it was so long ago that I no longer have the magazine to hand. What I do remember is that the chap in question researched the venue thoroughly beforehand, had planned escape routes and cut-off points where he would abort the run if he felt anything was amiss, it was recorded by a television crew (the Pilot article had stills from the film), and - as far as I can remember - the court regarded it as a genuine aviation exploit. I don't remember him losing his licence.
