Slashdot reader schwit1 writes that Tostito's corn chips "has developed a special bag, available for a limited time, that can detect if you've had too much to drink." Its all-black packaging measures your breath for traces of alcohol, and if the test reveals you're sober, a green circle appears on the bag. But, Mashable reports... If it decides you've been drinking -- regardless of how much -- an image of a red steering wheel appears on the otherwise stark black bag along with a reminder not to drive and a code for a $10 Uber discount (valid only on Super Bowl Sunday). And if you've had so much to drink that the mere act of hailing an Uber becomes a difficult chore, the bag will even do that for you. The package is equipped with near-field communication technology that will automatically order a ride when tapped with a smartphone.
