Autonomous vehicles rising

The days of self-driving cars clogging roadways continues to edge closer with numerous car makers, suppliers and even technology companies working toward putting more of them into service. Companies like Audi, BMW, Mercedes-Benz, Nissan and Delphi have all demonstrated their capabilities in this space, as well as tech giant Google with its own self-driving car project. At the beginning of the year, Audi sent a self-driving car from San Francisco to Las Vegas, then Delphi followed up with a cross-country, mostly autonomous drive. The question no longer appears to be if autonomous cars will ever dominate the roads, but when.
