Thank you for your detailed reply. I was under the impression that cars and buses were out of the question. This clarifies a lot. Ebikes and electric devices, however, sound to me like something futuristic, probably because I live in latinamerica.
Steep-slope places are not the norm almost anywhere, but they are not really that scarce here. We probably would need to make some technological catch up.
About elders driving, well, it’s common that they have cars although they can’t/shouldn’t drive them. Some younger ones can step in and volunteer, usually family members, but not only. An arrangement can always be made when young people hardly owns a car.
