15 years ago I had a neighbour that had one, used it commute about 3 miles each way to Leeds city centre and back. A relative of mine had their mobility scooter taxed and insured for road use, they had a UK driving licence.
My point is both were very cheap to run and were a great alternative to a car for them both, I definately think road legal electric transport e.g. Electric Motorbikes of the type we are complaining about has its place. Its now down to the government (

) to try and manage that.
