Next on the chopping block: the need for human drivers.

Google is behind this development. For years, they've been developing the technology to make automated cars a reality. They've also spearheaded lobbying efforts in Nevada, which just became the first state to approve regulations for testing driverless cars. This gives technology companies an official procedure for taking their self-driven automobiles out on public roads.

Now, companies must pay the Nevada Department of Motor Vehicles anywhere from $1 million to $3 million in order to test driverless vehicles. They must specify exactly where they plan to run these tests, and show that their cars will be capable of handling those environments. And unless otherwise specified by the Department, there must always be two occupants in the vehicle; one must be in a position to take control on case of an emergency. The state released a full set of regulations on their website.
