The big downside to me with CarPlay/Auto is that it doesn't leverage screen real estate properly. At least not yet. I end up with CarPlay/Auto on the main entertainment screen but with the manufacturer's system on the HUD and main cockpit screen - which I'd rather look at.
Because I can jump in one right as I exit the airport and get to my hotel cheaper than it costs to get an Uber that I have to wait X minutes for - and in LAX' case take a bus to get to. Just as an example.
I'm curious where this goes long term. Right now, in many areas, the money earned as an Uber driver is low. Consequently, the notion of being an Uber driver has shifted from "viable full time job with lots of flexibility" to "something you can do for extra money but cannot rely on to pay bills". As customers I'd expect us to continue to see the prices and quality of ride share to down - and many of us will revert back to traditional taxis.
