Plates that change numbers: avoiding radars and speeding fines

After our piece on the motorised numerplate to avoid speed radars which can be raised at the touch of a button, here is another piece of mischief designed to avoid radars.
An intricate mechanised system on this Ducati enables the rider to change a number on the plate on command.

While at a distance, a rider could probably get away with this mechanism, but up close at a road block, it would be difficult to pull off.
Thanks to giorgiogasss for the tip.
