Most modern "connected" cars can stream Internet radio, run Google searches, and navigate with GPS. But Cadillac is trying a more practical approach.

Starting late next year, the luxury car maker will add high-resolution streaming video to its rearview mirrors.

The concept—which will debut in the 2016 Cadillac CT6—is to eliminate traditional blind spots by removing obstructions like passengers, headrests, or the vehicle's rear pillars. A perfectly positioned video camera can improve the driver's field of vision by about 300 percent—four times better than a standard rearview mirror.

"The closest comparison to this kind of rear vision would be driving a convertible with the top down," Travis Hester, Cadillac CT6 executive chief engineer, said in a statement.

Compared to the traditional auto-dimming rearview mirror, Cadillac's video feed reduces glare and provides a crisper image in low light.

Plus, its 1,280-by-240-pixel, in-mirror display boasts a TFT-LCD screen, connected to an HD camera that was designed specifically to enhance rear-view lane width and maximize dim driving conditions.

"In addition to the increased field of view, the technology eliminates any rear seat, rear pillar or passenger obstructions, allowing the driver an unimpeded view of the lanes behind and traditional blind spots," Hester said.

Mother Nature won't cut you off, either: The camera comes with a water-shedding hydrophobic coating that promises clear visibility despite rain or snow.

And if you just want to peer out of your rearview mirror without any high-tech bells and whistles, just disable the mirror's video-streaming function by flipping a toggle under the mirror.

"The streaming video is a significant enhancement for the luxury customer interested in purposeful technology," Hester said.
