text: The current state of driving is very wasteful. Both the earth's resources and the driver's time are needlessly wasted. Sergey Brin has predicted driverless cars will use half the fuel of today's cars. This will have a huge impact on saving the environment by causing less pollution and removing the need to create as many dangerous oil rigs. The passage states that heads-up displays are a possibility in the future. These allow the person who would have been driving to do something productive. Instead of a long commute spent staring aimlessly at the road, a worker could finish a decent portion of his or her daily work in the time spent travelling to the workplace. Autonomous cars open up a huge new world of efficiency for everyone.
