It's not a big deal but the cars allowed on Uber has worsened. I remember trying to sign up as a driver a few years ago with a 2009 Corolla and being denied because the car was too old and now see cars from then allowed today. Maybe that's the cost of scaling but I find it worse. Also no more Uber pool.
I like Uber but I was surprised at how bad their mapping is - they get the route to get me home wrong and I've gone through the process of telling them about the mistake in their maps and they just seemed to ignore me.
