As well as private owners, both places have a car club using them too [1] - I guess it’s possible the low value makes them more attractive for that use.

I've seen a few in London, Nissan don't seem to market them very hard in the UK.

I've seen a few around Cambridge, very noticeable as a cycling since they sound so different.
