Also, most modern cars can be persuaded to display speed (digitally) in either mph or kph to suit your current needs.

Our recent hire cars have displayed the speed limit, as read from limit signs via their cameras. It is often wrong, displaying a recent speed limit, not the current one - unsurprisingly, since in France there are a variety of signs that set the speed (a crossed-out place name, for instance), the camera lens may be dirty, a lorry may mask a sign, and so on.
Apparently, the crazy EU has made this flawed system the basis for mandatory speed limiters (and the crazy UK has followed suit). If you run into someone stuck at 30 kph on a 130 kph autoroute, that's probably the reason.
"However, our experience of such systems suggests they can get it wrong. In one instance, a car's traffic sign recognition system picked up a 30mph sign on a turning off a dual carriage and dramatically slowed down, despite the fact the car was actually travelling along the outside lane" -
