While ADAS systems are effective for line-of-sight driving situations they can’t offer the situational awareness of vehicles that are connected to one another and the environment. Vehicles that are connected to each other can use their respective sensors to create a network of awareness that will extend far beyond the range of a single vehicle using ADAS alone. Connected vehicles will receive alerts of dangerous situations providing drivers and autonomous vehicles more time to react. For example, an oncoming car in the wrong lane in a blind curve; vehicles swerving to avoid a road obstruction; a driver about to run a red light as they are nearing an intersection could all be detected by connected cars that would transmit this information to other vehicles.

Connected vehicle technology will ultimately be less expensive to install per vehicle than ADAS systems and perform many, if not all the same functions. Connected cars will receive data from surrounding vehicles, and infrastructure, display driver alerts and interact with on-board braking, steering and engine management systems. OEMs, and high-tech players like Google and Microsoft are spending huge sums of money on research and development to create self-driving cars but they can’t get there without ADAS systems that will bridge the gap between current driver assist features and fully autonomous cars. Within 10 to 20 years, drivers will be able to get into their car and say “Take me home.” and read a book, or take a nap during the drive, but this will only happen in part because of ADAS systems that are used in today’s vehicles.
