I used to live in Paris and when I had visitors one of the highlights of their visit would be a drive around the city at night including a circuit of the Arc de Triomphe. Since traffic entering the roundabout has priority the technique is to drive at full speed straight towards the cars in circulation knowing that the old "priorité a droite" rule is instilled in the French from birth. Magically a gap would appear but then you would have to be careful at the next road because others would charge in calling your bluff in turn. From there I would race down the Champs Elysées and into the Rue de Rivoli from where we would go up the street where all the couturiers had their shops, YSL, Guerlain, Chloe, Chanel etc. It was important to be first away from the lights so if you were blocked by a car in front you would hit the horn if they didn't start moving within a hundredth of a second of the light turning green. For some reason passengers always seemed to clutch the sides of the seat and hold their breath. My brother-in-law once breathed a sigh of relief on arriving back at my flat and remarked "that's what you call precision driving." The final part of the tour of Paris was usually a trip around the several "pickup" spots where you could see some outrageously skimpily dressed women or blokes dressed as women and one spot in the Bois de Boulogne where cars would pull alongside and the couple inside would look over to see if you were interested in a little light wife-swapping.
Ah! Ce n'était q'un petit frisson!
I have an elderly French friend who still rides around the leafy suburb of Neuilly where I lived but no, the answer is that you never saw cyclists in Paris itself.
