The ride-sharing app Uber helped prevent more than 200 drunken driving-related deaths in 2019, according to economists who had access to the company’s proprietary data.

“When we do the analysis with that neighborhood-level data, which no one else has used before, we find … neighborhoods that saw increases in Uber see decreases in alcohol-related traffic fatalities,” said David Lucas, an economist at the University of California, Berkeley, and the co-author of the report.
