As a legally blind person living in the urban sprawl of LA, I rely on Uber and Lyft heavily to be able to commute and run errands. There is a lot about these companies that remains ethically and economically questionable, but until the public transportation options in the area are as quick and accessible as these services I will continue to use them. The pricing is the most unnerving thing for me. In some cases, I am now able to get an Uber for less than the bus. I am not sure how profitable that pricing is, but it is amazingly helpful that I can now go almost anywhere a sighted and licensed person can go and not have to carve out huge chunks of my day, plan for walking with potentially heavy loads or paying too much for this service.
Recently, I took a trip to Africa. It was interesting to me that even though they do not have a fancy app, you can walk out the door and find someone to take you almost anywhere you want to go. Part of our current situation is due to societal and cultural factors that don't necessarily exist everywhere. But, if we don't have Uber, I think there's still a market for affordable, on-demand rides.
