#4GPS traces aren't anonymous. If you go the same places often, your GPS trace is easily traced to you.

There's no indication that they are submitting the full trip trace.
If they only submit 500 meter long traces, it may he sufficiently anonymous.

I don’t know about Uber, but Apple has spoken about collecting similar data and they anonymize it by slicing the route into a bunch of little pieces, throwing out the beginning and end of the route, and anonymously uploading the bits in the middle.

#7What map data does Uber use?
I think they're making heavy use of Google Maps' API for the front end but what about the routing - do they roll their own or use Mapbox/Google?

#9S2 Geometry [1] is a pretty cool library for anyone who hasn't need it before and it doing map stuff. They mention it in the article half way through. Allows you to programmatically bucket GPS data and quickly search adjoining cells, etc. I was using this for a wifi project a while back and was pretty awesome.
