At some point, people waiting on a downtown corner realized they were being bossed around by a disembodied order:
"Wait!"
"Wait!"
The Waitbots (my term for the audible walk signals) are designed to improve the accessibility of the corners, along with nubby plates that provide a tactile reminder that the sidewalk is about to end.
But they're just another noisy element of the modern urban soundscape, which also includes chatty parking ramps.
There's no consistency to the parking garage voice alerts in Minneapolis.
Sometimes the voice is nervous: "CAR APPROACHING!" Sometimes it's bored: "Caution, vehicle exiting," said in a voice that made it sound as if the company got one of the middle managers to record it after a long lunch. There's one on 6th Street in downtown Minneapolis that sounds downright Bostonian: "Cawtion, cah exitin'."
But the more ubiquitous the automated voices are in an urban area, the more we learn to ignore them.
