cant say about Calais lately as we use the shuttle. as for our way we don't see them. there are a lot of bikers using the shuttle now, when you get off in Coquelle you are straight on the motorway when leaving the unloading ramps. we go across top and down via St Omer or sea side route Boulogne and Le Touquet. the advantage with the shuttle is you go through customs in Folkestone and that's it non stop when you leave.
likewise coming back you go through customs and passport control, then into duty free, go to the holding area , off the shuttle in Folkestone and straight on the motorway. all official bits done in France. not like the old days of being searched in Dover docks.
