The Download, Mar 27, 2017: Uber’s Self-Driving Smash, FBI Facial Recognition, and a Geoengineering Test

The most fascinating and important news in technology and innovation delivered straight to your inbox, every day.

Three Things You Need to Know Today

Uber’s Self-Driving Smash
The latest driverless car crash highlights concerns over robots and humans sharing roads. Uber has suspended autonomous car testing in Tempe, Arizona after one of its vehicles was involved in a serious accident that tipped its car. It's not quite another Tesla-esque setback, though, because police say that it was another driver, not Uber’s vehicle, that was responsible for the smash—so it serves as a reminder of a complex future where methodical robots and unpredictable humans must co-exist. Still, it's poorly timed for Uber: its self-driving division is undergoing a “mini civil war” according to Recode.

Researchers Prepare to Engineer the Climate
Geoengineering is back on the menu. The idea of using man-made techniques to ease the effects of climate change, by sucking CO2 out of our atmosphere or increasing how much sunlight the Earth reflects, is not a new one. But while popular among many scientists, skeptics have warned that such approaches could prove risky, because no one understands what their effects might be. Now, our own James Temple reports that a pair of Harvard climate scientists is finally preparing to spray reflective particles into the stratosphere.

FBI Facial Recognition Troubles
Smile: you may be misidentified. Last year, we learned that the FBI’s facial recognition technology made use of nearly 412 million photos. Now, the Guardian reports new details about the setup, explaining that around half of adult Americans feature in the database, with 80 percent of images originating from sources unrelated to crime, such as ID documents. Perhaps more worrying is that, despite the fact that facial recognition technology is incredibly advanced, the FBI’s matches are said to be wrong 15 percent of the time, and are (predictably) more likely to mistake black people than white people.
