Apparently not. There basically are no pickups, small or otherwise. The working folks use vans. Perhaps they view an open bed as ridiculous. Theft obviously is a serious problem in France. I've been on farms, no pickups, one sees one every week driving around, maybe, one a week or so. We were there for a month in Jan/Feb and I didn't see any. We drove around quite a bit, stayed in a small village about 60 miles outside Paris.
We were talking about how we were lucky not to have been there three weeks later. We returned Feb. 20.
