It depends on what "normal use" is. My car will passive regen almost continiously, that is the type of driving that happens several times a week for me, it only takes 20 minutes to passively clean a DPF, so the light has never come on. I believe the light is triggered by the differential pressure across the DPF and a 40+mph stint of 20 minutes + additional fuel injection on the exhaust stroke of the engine does an active regen, I have not achieved the level of soot in the filter to trigger it.
If a car requires an active regen on a regular basis it is not suitable for its type of use and a petrol car may be a better choice of car.
I have no idea how French cars work.
