It's be good if at the TCP level you could send multiple request packets across different connections on mobile and have whoever got back first was chosen for a while as the default. You have to admit currently this is very clunky. I would also add that specifically for things like Uber it'd be good to set very low network timeouts for Wifi and allow certain apps to suggest to the device they'd like to switch.
