Yes, lidar is probably a game changer for (indoor) navigation apps for blind people. However, I have yet to see a prototype which surpasses my own hearing. We shouldnt be too intusiastic about technologies coming up, and forgetting the skillset a human has already built-in... Tech is not always helpful, sometimes it is just an artificial gap between you and the rest of the world.

Blind man here. "for a few days"??? Seriously? This is like saying "If I only would wear a bra for a week, I could give birth to a child!"

I know blind people who wish their echolocation skills were better.

What I am trying to say: expect months or years for training, not days. Besides, it is not only blind people who have excellent directional hearing, conductors are forced by their trade to be able to point at the fiddle player they want to correct. So it is definitely a skill which can be picked up. But it takes some years to get to a level where it is useful.

Amazing case of newspeak. To call involuntary detainment at home "caring".

The irony is that vegans seem to care about the wellbeing of animals, but seem to forget to care about their fellow humans. Thats all. I can see how you feel this is a cheap shot. However, you are not the one who has been hurt by a fellow humans careless behaviour, so I feel like I have a little bit of an angle to this. People evangelizing run the risk of their other actions also being put on the scale...

No worries, if they knew what you are planning for them, cats would also be scared of you... Listening to (yours) cars mews is typically enough to read the message. Mine was pretty good at sounding anoyed and/or sugar sweet and/or helpless.

The biggest difference from otther obstacles is that bikes can fall over, and typically do so while landing on your foot or Achilles Tendon. It can also hurt mightily if you happen to ramm a handlebar into your stomache.
