Toyota demonstrates self-driving car at CES 2013

Someone would have to sit down and do a really deep think through of existing road laws and regulations when self-driving cars become more and more commonplace. What happens when the data received by the vehicle is incorrect, and the car actually breaks the speed limit, all the while when you are sipping on your Starbucks mocha at the back seat, reading up on all that is happening in the world on a tablet? I suppose humanity will cross that particular bridge when they arrive at it, but otherwise, it remains something to chew over at this point in time. Toyota has already demonstrated a self-driving car over at CES 2013, although there are still some lengths to go before something like this is perfected for everyday and safe use.
