Self-driving cars are developing at breakneck pace. Although considered to be a major breakthrough in the application of internet of things technology, there are still many safety concerns associated with the cars, as they are still not intelligent or intuitive enough to make proper judgments on the road.

In order to ensure road safety, the cars may need a more powerful internal navigation system that provides every possible detail about the traffic situation.

BrightMap, one of China's top e-map manufacturers, demonstrates just how much easier and safer it is for self-driving cars to operate with the help of a 3D high-precision map.
