Well... sort of. The British licensing issue of 3 wheelers went back to before WWI, and had more to do with tax rates than driver training. Post WWII, all of Europe was financially weak and fuel costs high, so microcars were what the masses could afford. In the UK, 3 wheelers remained cheaper to MOT than standard cars which is why they were popular. The "extra test" had little to do with it AFAIK, perhaps British UCPers could enlighten us. Reverse trike arrangements work fine, but the shopping cart arrangement not so much. The last Bond was the Bug which retained the tippy and poor-handling layout for some reason.
