> basically a form of technical debt Or left there for future flexibility. A crosswalk near me was just switched to where the button does nothing. (You can tell because now the walk signal shows on every cycle of the light. Previously, it would be skipped if you didn't push the button.) If they had removed it, it would make things harder if they ever want to reverse this decision. They'd have to reinstall the buttons, which could involve locating it in storage or even buying a replacement, plus sending out a crew, etc. And there are signs that go along with the buttons, so you've got to make sure those are reinstalled correctly. Not insurmountable problems, but they have a cost, and it's not clear this would be the best use of limited money.
