This is pretty cool: Uber Trip History Bookmarklet.
It allows you to get your complete Uber trip history, download it as a CSV file, and then run the Uber Data Visualiser. You get to learn quite a bit about your trips. I’ve attached a snapshot of mine, there’s more data and you should run it too!
Would be interesting to see this kind of history for Grab rides (and all the other various ride services out there).
