All the tech hype you hear about for cars recently seems to surround self-driving cars. Not surprisingly, as it is very sexy tech with a Blade Runner type feel. People love it when technology advancements mirror sci-fi movies they used to watch as kids.
I find this type of technology much more realistic for implementation in the short-term (like the next 10-20 years), and will probably have a profound and significant impact on how we drive and potentially keep accidents at bay. (and how police forces monitor our driving behavior)
The technology is called dedicated short range communication (DSRC), and it's basically IoT (Internet of Things) tech that allows cars (and other things) to connect and communicate together wirelessly. Your car can tell you when another car is about to collide, warn you about when a car is stopped in a road or an accident has occurred, automatically dispatch emergency crews and divert traffic from accident scenes, amoung other nifty things.
This tech operates at 4.9 GHz and can communicate to other cars your speed, direction and position. 10% of new cars are expected to have DSRC by 2018, and 70% of all cars are predicted to have this tech by 2027.
As expected, the initial marketing around this is to save lives and prevent accidents, but what happens when your local or state police department start tapping into these networks, and you now get automated tickets for breaking a speed limit? Cha-Ching!
