But the relationship between binge drinking and ride-sharing apps may be more complicated than that. If you know you can get a safe ride home from the bar, the thinking goes, maybe you'll stay for an extra round. Or five.
A study by a team of researchers from the University of Louisville and Georgia State University found that alcohol consumption and binge drinking rose by three and eight percent respectively in cities where ride-hailing services become available, the Economist reports. Interestingly, in cities without public transport, the effect was even greater.
The researchers used data collected by America's Centres for Disease Control and matched it to when Uber became available in major cities. A paper of their research was uploaded to the research repository SSRN last week and has yet to be peer-reviewed.
A different study, from February, found that the number one reason people chose to grab an Uber was so that they could drink. In 2015, the LA Times also reported that ride-hailing services were linked to a surge in alcohol consumption.
Despite the data, it's important to note that there's still no direct evidence of any causal link between ride-hailing services and binge drinking. Previous studies have tried to link a decline in DUI-related incidents to the use of ride-share apps, but the relationship is far more complicated than that.
"DUI is a complex subject with many causes," Chris Cochran of the California Office of Traffic Safety told the LA Times in 2015. "To be able to postulate whether the advent of Uber or other ride-share services had any significant effect would be difficult if not impossible."
