Car-to-car communication, or Vehicle-to-vehicle communication (V2V), is new technology that has life saving capabilities. This is done through cars, essentially, talking to each other alerting other cars of its speed and whereabouts.

Techradar.com gave a great example of your car telling you to stop your car at a junction then, unknown to you, a car came speeding round the corner, which if it hit you could have killed you. 

But, how did your car know to tell you to stop?

V2V communication. The speeding car, not the driver, informed all cars within a certain radius to not go on certain roads at certain times. This can be done through street vibrations or a notification on your radio screen. This, however is not the same as self-driving cars.

Unfortunately people break the law all time when driving, be it on their phone, DUI, or generally being distracted causing reckless driving. This technology can predict and protect you from impending accidents. We may also see this technology in the likes of self-driving cars, which while car-to-car communication would be helpful in those cars, it shouldn't be relied on 100% as sudden changes in the environment and the unpredictability of Human drivers could case these cars to crash, despite the V2V communication. 

With the emergency services travelling at high speeds and the ability to skip red lights, be it deemed safe to do so, car-to-car communication could be used to inform other vehicles that could potentially block the route, or impact the vehicle from around a corner, or at a junction, to move out the way providing a clear pathway for the vehicle to pass through, alternatively it could tell on-coming traffic to slow down or divert their route to avoid such a collision. This could, if implemented with self-driving cars, to move parked self-driving cars out of the immediate area of the target person to ensure that they arrive at the incident as fast as possible.
