Warning: These signs from the future are closer than they appear

“Keep left lane free for driverless cars” and other futuristic signs are just around the corner

With our quickly evolving modern-day electronics, it won’t be long before the world as we know it is left behind in the rear-view mirror. From the restriction of smart devices in specific areas to neighborhood-watching drones to lanes on the highway meant for driverless vehicles only, scientists and major technology companies could shift what the world looks like in just a few years, and these signs of the future predict what the world will be like with those advances.
