Interesting Express Pool experience today in San Francisco - dropoff order changed mid-ride.

I'm picked up in the Lower Haight, going to Rincon Hill. There's already another rider, and the Uber app indicates he will be dropped off first - in North Beach. Whaat?!

Many SF roads are closed today for a marathon. The driver ignores Uber navigation and takes his own route up Market Street. Somewhere around Montgomery, I hear a chime and the driver's app announcing a route change. I open the Uber app on my phone and it now says I'll be dropped off first. The driver makes a right turn and I'm out shortly thereafter.
