I would feel much safer if Uber didn't have the information in the first place. Despite their damage control spin, they have no legitimate need for it.
Except for that little tidbit of needing to know where to pick you up and drop you off so they know how much to charge you for the ride.
I don't use taxis nor Uber (I've been in a taxi once in my life).
So, obviously, that qualifies you to comment knowledgeably about a taxi/Uber issue. SMH.... The level of discourse here has seriously eroded.
