Jonty,
Yes you can!
For those unfamiliar with the concept of a "sans permis", this is a tiny car, of restricted engine size and speed which can be driven without a driving licence or without a registration plate. They are also known as a "voiturette". To get some idea of size think of a Nissan Micro and divide by two! An old guy near here still drives one with a single cylinder, you can here it coming and going from a vast distance. Modern design has much improved their looks. They are sold in quite large quantities. We have a local sales place that sells nothing else.
I would imagine they are peculiar to rural places and appear to be favoured by the elderly and the disabled.
