Last month Nevada became the first state in the union to approve and register driverless cars for use on state roadways. California was close on their heels, approving a state senate measure meant to allow the use of these vehicles on state roads. That means autonomous cars, completely controlled by on-board computers are now perfectly legal in these states. And that is just the start of their progress.

These autonomous vehicles are being embraced by legislators, safety experts and the automotive industry, all whom say that driverless cars would increase safety on American roadways, decrease collisions and improve the flow of traffic. they would also enable people who might not otherwise be able to get around on their own, to get where they are going without fear of danger. These dangers include an inability to safely operate their vehicle due to a physical deficiency such as poor eyesight, or even, allowing the vehicle to drive you home after a night at the bar.

Now four other states have joined with Nevada and California, and are considering measures which would allow the use of autonomous vehicles on state roadways. Arizona, Hawaii, Florida and Oklahoma are each considering legalizing the use of autonomous vehicles.

Google has been working diligently to enhance and perfect the technology which allows these cars to operate themselves for the past decade. The technology is now ready for commercial use and these cars are already getting work. As a demonstration, Google gave an autonomous vehicle to a blind man and he used it to drive himself to Taco Bell for lunch. This very public demonstration seemed to solidify company claims that these vehicles were not only safe to operate on public roads, but actually ‘safer’ than letting humans get behind the wheel.

However, every autonomous vehicle comes with a manual override switch which allows the driver to take control of the vehicle with the push of a button. So, if a drunk driver gets behind the wheel and decides to driver himself home, the vehicle won’t be able to stop him, meaning we might not be as better off as we hope we will be when it comes to controlling stupid drivers.
