I had read this thread a while back with great interest as I wondered what licence rules might apply in Australia if the 3 Wheeler went on sale. I understand the current compliance process is being done on the basis the 3 Wheeler is a car and not a motorcycle, hence the requirement for three crash tests. I have also read the changes required to meet Australian car standards include higher roll over hoops behind driver and passenger that incorporate head rests. So it seems that if the 3 Wheeler passes compliance it will be classified as a car and a standard car licence is all that will be required to drive one. As a car it will also be exempt from motorcycle helmet laws. On the down side it will be subject to our ridiculous luxury car tax that will push up the purchase price. I know this doesn't help UK & European markets but thought it might be useful background info.
