Why does the Dassault Falcon 7X's cockpit have ashtrays? While looking at the first implementation of Fly-By-Wire systems, I see that the 7X was the first business jet with fly-by-wire controls.
Looking at the Wikipedia page for the aircraft, I saw this photo of the cockpit and noticed the ashtray in front of the sidestick on either side:



Why would there be an ashtray in the cockpit?
The Telegraph states that they are still present in aircraft toilets due to a FAA regulation that requires an ashtray be present in the event that a cigarette is lit and needs to be extinguished. However this doesn't cover the flight deck, surely the FAA doesn't assume a pilot will light-up during flight?
In the United States, the smoking ban only applies universally to air carriers on scheduled flights. The regulation states


  §252.4   Smoking ban: air carriers. Air carriers shall prohibit smoking on the following flights:
  
  (a) Scheduled passenger flights.
  
  (b) Nonscheduled passenger flights, except for the following flights
  where a flight attendant is not a required crewmember on the aircraft
  as determined by the Administrator of the Federal Aviation
  Administration:
  
  
    (1) Single entity charters.
    
    (2) On-demand services of air taxi operators.
  
  
  (c) Nothing in this section shall be deemed to require air carriers to
  permit smoking aboard aircraft.


So for essentially all of the Falcon's missions, such as Part 91 corporate flights, and private charters under 10 passengers, smoking is permitted, as long as an "adequate number of self-contained, removable ashtrays" are provided (14 CFR 23.853(c)(1) or 25.853(f)).

Said ashtrays from a factory photo:
