Can wireless connectivity make self-driving cars safer? [NOVA Science Café](http://www.sciencecafes.org/what/) hosts Worcester Polytechnic Institute (WPI) professor Dr. Alex Wyglinski. He explains the current state-of-the-art tech in vehicular wireless connectivity. Learn how vehicle-to-vehicle communication improves situational awareness of the road environment for self-driving vehicles. Although almost all self-driving vehicles rely on sensor technologies such as LIDAR, RADAR, and vision systems to gather data about the surrounding road conditions, wireless connectivity between cars and nearby infrastructure is often overlooked in the discussion about autonomous vehicles. For even more on self-driving cars and to see how they are being tested, check out [NOVA's "Look Who's Driving"](http://www.pbs.org/wgbh/nova/video/look-whos-driving/) — an episode that explores the challenges of training artificial intelligence to be better than humans at making life-and-death decisions.
