Uber employee here. We were told the reason to track up to 5 mins after the trip is for fraud, ex if a driver doesn't end the trip when she is supposed to. and to figure out where the pick up spots for each address are. A large building may have multiple points where people get picked up or dropped off and knowing those points would be very useful for the drivers and riders.

And just as a side note, take it with a few grains of salt but I know it's not easy to just trust a company with such personal information, and certainly I wouldn't either, but Uber as a company is very ethical and takes the responsibility that we are entrusted with very seriously.

There are a lot of things we do for our customers that isn't reported by the news, but we always try to do the right thing. Ex. When we had a few outages earlier this year, we made sure that the drivers who were active at the time were "made whole" by paying them for the time we were down.

Yes, there were issues a few years ago with statements and actions that were done, but the Uber today and the employees that work here now take a lot of pride in what they do. I would never have worked here if I didn't feel Uber was an ethical company. And neither would my coworkers. There are thousands of engineers now working here and we would be the first ones who would stand up to management if we felt that something nefarious or even careless was being done with user's personal information. Many of the company values revolve around "toe stepping" and "principled confrontation" and this means even against our own management.

So I know it's not easy to believe, and it's easy for me to say since I work here, but nothing nefarious is going on. If there was, we the engineers would be against it completely.
