streetlight

For example, piezoelectric sensors in roads could detect the motion of vehicles to track traffic or to light upcoming road signs or streetlights as needed.

After the city agreed to pull the funding for the streetlights, for example, we learned that it’s not actually possible to turn them off completely.

Local governments have routinely acquired and deployed new technologies like smart streetlights without fully considering how the information collected could be used, or the biases embedded in the technology.

In San Diego, the streetlight system became exclusively a crime-fighting tool after the City Council defunded it.
