General

There is perhaps a dozen or two crossings with a vibrating button in Czechia but users have mapped 400+ of them, almost exclusively via StreetComplete, and several have admitted in messages that those were mistakes. I find the wording of the question (in Czech, English and German) pretty clear but that could be because I have encountered tactile buttons before. There seems to be confusion of the icon with tactile paving (since the current icon shows a blind person feeling with a cane), sound or other quest. Some users native to Germany also habitually click "Yes" because vibrating buttons at traffic lights are the norm there. Therefore, I suggest one or more of the following solutions:

1. Hide the quest in Czechia by default
   • to map the few vibrating buttons, users could re-enable it in settings, use "Edit tags" in SCEE or simply use another editor
2. Add an "Are you sure?" confirmation to "Yes" answers
   • "Such crossings are rare and buttons with that function often cannot be distinguished by sight alone. Did you check that there is a tactile feature indicating the state of the traffic lights?
3. Change the current icon to more closely reflect the "feel the button with your hand" nature of the feature
   • I'm not a graphic designer. Please get someone to make graphics that:
     • Fit the existing design style
     • Reasonably cover the regional variations of the feature
     • Have reasonable file size (<5 kB)
     • Are clear and legible at about 25 px resolution, which is true for the existing icon set
   • Anyway, here's my suggestion:
     • StreetComplete_quest_traffic_lights_vibration_proposal.svg
     • Also change the button_operated quest to match the design:

The discussion in the talk-cz thread (in Czech) is ongoing.
