40 years ago we thought(well,some of us did) that accurate image recognition is a matter of few months of work, at most. It&#x27;s 2016, and our most advanced image recognition software can&#x27;t tell a zebra and a sofa in a zebra print apart. It&#x27;s an insanely difficult problem. We can&#x27;t even do voice recognition completely right. Automatic cars rely on that exact type of challenge - recognising patters accurately. I&#x27;m sure in certain settings they work exceedingly well. Spectacularly even. But to be safe for human transportation, they need to be 100% accurate. Not 90% or 95% accurate. They need to work in snow, rain, when a huge sinkhole appears in the ground or an infant walks into the road. They need to consider legal, moral and ethical implications lest they be allowed on the road - is it allowed to hit a pedestrian to save 4 passengers? Is it allowed to hit 4 pedestrians to save 1 passenger? 
Can you at any time take manual control? If yes, how do you regulate insurance? If no, how do you tell the car that you want it in <i>that</i> particular spot and not any other, be it your garage or a middle of a clover field?<p>Yes, there already is software that can drive safely on lit, dry roads, while there is a human behind a steering wheel tracking its every move. But I still believe we are at the very least a few decades away from fully autonomous vehicles.
