Another day, another feel-good stunt from Coca-Cola. This time, it enlists agency DAVID to spread some Christmas cheer in Italy. As people wait in line for cabs in a holiday rush. a taxi outfitted in Coke colors pulls up and picks up people. It then broadcasts its destination on a little screen, so other people who might be going the same way can also hail the cab. Passengers inside make new friends, and share some Coke too.
