Dino - if you've not done so, suggest you read this thread from post 1 which I made.
You are right in thinking it's a daft idea, the club has not given up although where one goes now is not clear. The Minister for Transport has seen my letter stressing the safety aspects`but the reply is along the lines the EEC is to blame and the 'grandfathering' is a concession.
Correspondence I've seen says the UK representatives did not want trikes to change from B1 but were voted down by the rest. However real information from that time is hard to come by and I still cling to the belief that the EEC think a trike is a motor bike with a back axle, not a car with a wheel less.
