Even old blind people who can’t pass driving tests use Uber or Lyft, because public transport simply isn’t safe or suitable enough for them, especially during grocery runs.
You are assuming a car centric city here. In a walking and transit oriented city, it is safe and suitable for blind people to be independent and move by themselves. Only cars make the cities unsafe and the lack of transit makes it unsuitable to use something else than a car.
Public Transit my beloved 😍 (lemmy.ml)
