Mini-Moles are proper cars aren't they? It's basically a Mini. Motorised wheelchairs are often a bit of a nuisance but they are an order of magnitude less car-like than a VSP.
I though that mini-mokes were 'baby' motorbikes. The point about motorised wheelchairs is that they aren't registered as far as I'm aware.
Slight tangent here: one of my godfathers, and our family doctor, had a really old-fashioned disabled vehicle that had belonged to his mother (this was in the 1960/70s). It was an elongated 3-wheeler and the driver was meant to pedal it whilst reclining on the seat, with their legs out in front of their body. I can remember driving it from his house/surgery to ours - a distance of about half-a-mile - via two of Oxford's busiest roads when I was about 14. 'Hairy' doesn't do the trip justice. Cars were racing past me, and trying to steer it into the middle of the road to turn right was not easy!!
