This. When Musk came up with his hyperloop idea, I found it odd. It seems to me that transportation nowadays needs two things : supersonic airliners and self-driving vehicles.

The ideal scenario to me is this:

   1. wait for a self-driving car to pick you up,
   2. be driven to a subway/train-station,
   3. take a train to the airport
   4. fly at supersonic/hypersonic speed
   5. repeat previous steps in reverse
