Safety improvements could be so great that insurance rates would drop by over 80 percent, or disappear altogether, consultant firm Celent predicted last year.

Robot cars are more efficient

Cars spend 90 percent of their lives sitting in a garage or parking space instead of out on the road. Even when they hit the road, their human drivers space them so that only 5 percent of a highway's surface is occupied when running at peak throughput.

The Texas A&M Transportation Institute estimates that traffic congestion annually wastes 4.8 billion hours and 1.9 billion gallons of gas, which translates into $101 billion in lost productivity and fuel costs.

A recent study by the Institute of Electrical and Electronics Engineers found that AVs would increase highway efficiency by 273 percent. Computer controlled cars could drive much closer together at higher speeds, reducing congestion and improving fuel efficiency.

A car that drives itself is not only more efficient, it makes the driver more productive. The Census Bureau says the average person spends 25.1 minutes commuting to work. AVs would reward commuters with an extra 50 minutes every day.

Robot cars will improve mobility for everyone

According to the Census Bureau, there are more Americans age 65 or older than at any time in U.S. history. While senior citizens would certainly benefit from AVs, so would the blind, the disabled and even tweens.

The IEEE predicts that driverless car-sharing programs will dramatically change the mobility of people of all ages and abilities. As fully automated cars become commonplace, the need for a driver's license could disappear, making it easier for both the old and young to get around.

Futurist Thomas Frey, executive director at the DaVinci Institute, predicts that automakers will shift from building cars to providing transportation, charging a per-mile fee. Why own a car when a push of a button can bring one to your door, drive you to your destination and then disappear. Frey believes that automakers will eventually start promoting the "rider" experience of their vehicles instead of the "driver" experience.

The government wants you to have one

All of this change will require the approval and support of the government. Nevada was the first to license autonomous vehicles. (See " Self-driving cars: You can text, but you can't drink.") Florida and California quickly followed suit, and others are considering it.

The federal government is also getting excited about the possibilities. David Strickland, head of NHTSA, has said that autonomous vehicles could be a "game changer" and has referred to them as the next "evolutionary step" in car technology.
