This design assumes that mobile is equally bad across all user locations around the globe and across all devices.

The key issues are bandwidth (which varies greatly) and the device's ability to decode video of different sizes in real time.

A more appropriate way of providing UA-selected alternatives would be attaching a Media Query to each <source> and extending Media Queries to query bandwidth and some kind of decode performance metric. (Unfortunately, the latter is probably hard to represent as an intuitive and easily measurable scalar.)
