Those Yellow Dots at curb ramps.
 

Does anybody struggle to get across those yellow dot panels in the sidewalk at curb ramps?

They are an accessibility barrier to many.

Some may struggle to focus on the pattern.

Some may struggle to maintain balance on the uneven footing.

btw, These yellow dots, officially called truncated domes or detectable warnings, are intended for the blind and visually impaired but even the blind do not like them.
