I am not sure how the regulatory authority can control how many hours a pilot chooses to travel on a bus (outside of his duty period).

I was thinking the same until I sat through the programme. My French isn't the best but as I understood the dialogue the pilot seemed to be claiming he had no choice in the matter. The claim seemed to be that pilots were regularly operating "open jaw" trips, and were being positioned back by bus/taxi to the trip originating point, umpteen kilometers away, at the end of the day...and there was a hint that time spent on such positioning wasn't being factored into the calculations governing the start time for the next duty....
Of course it's a TV programme so who knows the reality......
