CEO Anne-Marie Slaughter was just in the On-Point podcast saying the same thing (in context to work-life balance and family), that we have a bias for thinking the person who comes in at 6am and leaves at 6pm is a good worker.

Coordinating this is a hassle. With driverless cars, you could say "I need a vehicle to take me from A to B" and a vehicle just shows up, possibly with one or more passengers who were already enroute to B.

Both have attempted to do what you are talking about, but have settled on something more similar to "Walk to checkpoint A and wait for 5 minutes and you'll be dropped off at checkpoint B that is kinda close to where you actually want to go".
