A new thing that was created on december 15 was beacon for Uber. A lot of people have beeen getting into the wrong car when they get an Uber. Now there is a addition to the app to track your Uber and a green light for the driver to put in their car. I think this is a good idea because one time i had trouble when I got a Uber for the first time. A question I have is does the green light cost money to get?
