The iPhone app that lets you find open parking spaces in a city that has embedded sensors at 1,000s of spaces.

What a great fact pattern for a torts exam!

“It could be really distracting,” said Daniel Simons, a professor of psychology at the University of Illinois, where he studies the science of attention. And, he said, it could also be dangerous: “Most people are looking for parking spaces in places that have a lot of traffic and a lot of pedestrians.”

City officials acknowledge the potential problem. They are urging drivers to pull over before they pull up the city’s iPhone app, or to do so before they leave home. 

Before they leave home! But the sensor sends out its signal seconds after the space opens up in an area where drivers are circling looking for spots to pounce on before the next car snags it. That's why installing the sensors seemed to make sense in the first place.

Nathaniel Ford, executive director of the San Francisco Municipal Transportation Agency, said safety could actually improve if drivers quickly found a spot instead of circling and getting frustrated. “I get you off the streets as quickly as possible,” he said.

San Francisco spent $20 million on this system, not counting the money they will spend on struck-pedestrian law suits. One way to get a person "off the streets as quickly as possible" is to... ugh! Sorry to go morbid on you. Technology is cool. San Francisco is cutting edge... cutting down traffic... and hopefully not pedestrians.
