These are usually called LSVs; the number of these is low but growing because in dense urban areas or planned developments (golf courses, parks, senior communities) they're far more cost effective.
counterpoint: I have an EV that I never drive more than 77 miles a day and I paid over $70k for it. Top speed would definitely be a limiting factor, but I do think there's a huge gap in the mobility market between e-bike and a traditional (and expensive!) car.
