A few weeks ago I had a chance to temporarily become a guide for a #blind person and I must admit, it makes one see the surrounding infrastructure in a completely new light, because normally we don't think about it at all.
It also really shows off how badly designed #accessibility of public spaces can be.
Every time I interact with public transportation I'm annoyed there are no or insufficient audible clues for vision impaired people, or visual information for deaf people. It somehow is always only either one or another. Or even none at all.
And it's just a tip of the iceberg of accessibility problems, there are huge numbers of other issues that I'm not even aware of.
It's hard to believe to be honest.
