Yes, it legitimately is an accessibility nightmare.
There is a blind man I used to follow on YT. He is American and is pretty self sufficient. But since there are literally zero distinguishing features on our paper currency for blind people, he manages to know which bills he has by hoping others are telling him the correct bill in good faith and then organizing the bills in a particular order in his wallet.
Yeah I drive around 3 hours on the highway every several weeks. Sometimes on my drive, there’s obviously traffic. A lot of times it will be something like rush hour traffic, a crash, construction, etc.
But then like…a good portion of the time when I come to the very front of the “clog”, I find that it is just a blockade of multiple people going incredibly slowly and taking up all lanes of traffic, refusing to move over despite the fact that they are going under the speed limit.
