A photo of an Acura RLX towing a second car has been making its rounds on the Internet recently. Now, there's nothing unusual at first glance... until you notice that the vehicles were not physically attached to one another! The second car drives itself as it follows instructions beamed by the first one.

Car developers had been very enthusiastic about building cars that can drive themselves. And now they are focusing on creating automobiles that could talk to one another in an effort to introduce a whole new level of convenience for its customers.

General Motors Co, Honda Motors Co (which owns Acura), and other automakers were reportedly working with both traditional suppliers and startup firms to make the convergence happen.

Tech giants Google and Apple had been leading the pact in terms of innovation. Google was known with its pioneer work on driverless cars while Apple, on the other hand, was working with automakers to embed greater connectivity in their cars.

Price may be steep, but recent studies show that car buyers are willing to pay up to a whopping $3,000 to have hands-free driving capability. No wonder as self-driving cars was not only convenient, they are also expected to be less expensive, more fuel efficient and safer.

For example, the Chrysler Group charged nearly $3500 as part of its SafetyTec package on its new 2015 Chrysler 200C sedan. One of its most popular features is the Active Park Assist system that can detect and steer the sedan into any available parallel or perpendicular parking spot. The package also includes a number of driver-aid and safety features such as a pre-collision system, which automatically activates the brakes when it detects an imminent forward collision.

How about you? How much would you be willing to pay for a self-driving car that can talk to one another?
