The test (and the measure of success) will be to get one to negotiate the Place Charles de Gaulle (aka the Place de l'Étoile, where the Arc de Triomphe sits) in Paris. They can run a test round Hyde Park Corner and when that is successful they can head off to the French Capital.
Over the years many French traffic experts have tried to devise schemes to tame the traffic round that giant roundabout and all have failed, declaring it is best to let drivers get on with it. It is my opinion that there is no software likely to be available in the foreseeable future which will enable a driverless vehicle to safely negotiate that junction and until it is the concept should be restricted to tests on private land such as disused airfields.
