"The Pee Analyzer" from DDB Group Singapore remind me of the McFarland Beer Pissalyzer , which might not have been as hight tech, but it was telling people to cab it in May 2011.
Still, DDB Group went so far as to connect the pee-er to the RFID car key-tag, and measured the alcohol content in the urine at the urinals. When someone who tested as "too tipsy; should taxi" arrived at the valet to get their car, the RFID tag would remember and flash red: this person should use a car service.
This piss test was so successful in preventing drunk driving that the system now rolls out in bars and clubs all over Singapore.
Next step - measuring for drugs. I kid. Also, do girls not drive in your world?
