Some conditions don't exist in many places. Someone can have a self-driving car and use it for life in Arizona and it doesn't matter that it wouldn't work in Alaska. It's still progress and still useful to a subset of people. Hell, even a car that works 9 months out of the year in the Northeast would be useful. Don't see too many bikes out when it's -5 degrees but no one is claiming bikes aren't useful.
