I’ll post part of it here as well.

traffic circles can be extremely dangerous and confusing for blind people. I had a friend cross one, and barely made it through, but didn’t end up at the right corner, and he got confused. My instructions when I got training on crossing streets was, a strong “do NOT cross, find an alternative or get some help. Whatever do NOT cross it by yourself.”

As to your silent car issues. Again, maybe because I am old fashioned, I do not trust the audio signal. Listening for cars at the right intersections are safer. Audio signals can break, malfunction, and I personally don’t trust them or find them to be reliable. So much for trusting technology, I heard a self-driving car just ran over a lady in Arizona. I love technology, I collect it, but out in the road, I am unsure how much I really trust the stuff to get around. GPS is fine for the most part, but I often ask for help. Several times, it’s marked wrong on the maps or the place is non-existent or not a real place. So, be careful about trusting technology. You’re putting a lot of faith in technology when you cross using the audio signal. What if Joe ran a light? With engine noices we can hear. Some drivers just don’t care. Yeah, streets are dangerous anyway, and everytime I cross one I do risk, but I would think I can react faster if I find mid crossing I hear joe speed toards me or if I hear him surge, or whatever. If I hear him go past me despite a red light, I won’t cross till after he’s gone. I also can spot errors in the traffic signal or a broken signal if I can hear what the cars are doing rather than just reports of the signal. Also, while crossing many of us veer when crossing. I use all the noises on the cars on my left to keep me straight half of the time, thus being very safe. So, Blind people not only uses engine surges to cross the street. I think too only needing to keenly listen just before you step down from a curb is just not how it goes.

My father says until every car is electric/noiseless, they should have noisemakers of some kind because even if the electric car makes an audible sound, it will be completely masked by the sound of other non-electric vehicles. He has a small story, once while crossing a crossing without lights, there was a very quiet (hybrid?) vehicle just behind a large 4-wheel-drive, and he could not hear the sound of the hybrid car over the sound of the larger one; he nearly got hit because he couldn't hear it.

OP of that post said that the blind population can rely on buttons and lights to cross streets after previously highlighting how some crossings/intersections don't have buttons and lights. How are blind people supposed to cross those with silent cars streaming through?

Im not blind but i can only assume this would make things a lot more dangerous

If we get any complaints about brigading this post will be removed.
