They certainly used to but those days have long gone. That was when they had motorbikes and sidecars as well as yellow phone type boxes
It does remind me of an occasion in I think Belgium when we on our Lambretta 150cc were passed on an almost deserted newly built dual carriageway by a Touring Secours motorbike and sidecar. The driver waved as he passed with both feet on the handlebars. Must have had some arrangement to hold the throttle remotely.
A few of the old boxers are still around I know of one on the way to Fraisthorpe.
