I think we need more electric Velomobiles on the roads. It's just a shame that they really don't fit existing US and EU regulations. Perhaps they could be licensed as Quads, but I suspect there's still a whole load of awkwardness around insurance, let alone TUV and MOT testing. I think something that can do 50mph should require safety checking, be licensed and insured, but I also want this to be easy for one-off or low production quantities.
