I used wifi on a flight for the first time a few weeks ago- it was fantastic. Not perfect, but it converted six hours of dead time into productive time.

It got me thinking about how driverless cars will represent a similar change. They seem like they are one technical innovation that we'll definitely see in my working lifetime, and I'm looking forward to it. Imagine being able to start and end your working day on a laptop in the car, rather than wasting time commuting.
