If you are interested in autonomous cars and you aspire to be one of the first owners when it is finally released then you may want to research them through reliable websites. An autonomous vehicle would allow you to travel in your car without actually driving yourself as the various sensors that have been built in are designed to take care of everything for you.
However, it is still in its initial stages as different companies are competing against each other to be among the pioneers of such cars. Google, Uber, Kia to name but a few, are all showing a great deal of interest in autonomous cars. It is an interesting field to follow closely.
You may find it helpful to refer to this article at http://www.trippinwithtara.com/what-is-an-autonomous-car/ that would give you an idea on what these cars are all about and when they can actually be expected to be available. Things may not be as easy given that, a number of considerations have to be made when making such cars available for purchase by the general public.
This is perhaps the reason why no such car is available yet that can claim to be able to safely drive without intervention from the part of a human driver.
