Since it would be one software being used many times over, I'd be fine if it could pass a large number of driving test with very low failure rate, considering driving tests are quite random in how they are applied. The question is however which driving test. My experience in Switzerland was that the practical driving test was quite hard to pass, I had to train a lot to satisfy them completely and they route you for one hour quite randomly around a European medieval town and its outskirts, i.e. a place that's quite hard to navigate correctly as it's not built for cars.
