Pay the officer who stopped you, at the side of the road? Wow, sounds just like Baja California.....
I traveled fairly extensively throughout France, Italy, Germany, Portugal, in 1972. Never got stopped. Broke the law a few times, but it is hard to speed when you're driving a VW camper converted to carhauler, towing another Formula III on a trailer.... Use common sense and courtesy driving and you will have no problem there....
