Oxford scientist are working on a system for autonomous vehicles which doesn't rely on GPS for navigation.  This means that the technology can find a wide application - from warehouse fleets to Mars rovers. Even if you have some reservations about autonomous cars, imagine how the technology can change your life.

Two things that pop in my mind are reliable car travel for my work commute eventhough I am not a confident driver myself and long road trips without the need for my partner to worry about finding a co-pilot!
