These types of services just don't get thrown together in a couple of days in reaction to a competitor, they require a lot of work and engineering to implement properly.
I'm sure both Uber and Lyft were aware of this feature being designed by their each and are trying to get their respective features out the door.
Ever notice how AWS and Google release price decreases within the same days? Same thing. They have been told it is upcoming and are doing the same thing. I've seen it personally.
