It is reported that Navion will probably become the representative of the next generation car navigation technology. The laser will "draw" road maps and route guides on the windshield. Because there is no need to bow, this will be the safest navigation technology. Another good news for consumers is that they can buy equipment directly for old cars instead of buying a new car to enjoy this navigation technology.
Although you can get the driving route without leaving the road, this navigation technology also has a defect, that is, it needs the driver's gesture to control the start and stop. During driving, leaving both hands or one hand off the steering wheel will bring a certain degree of danger.
It should also be pointed out that in some countries, this technology of projecting navigation information onto the windshield still faces traffic legal obstacles. It is reported that some countries require people not to have other objects blocking the line of sight of the windshield while driving (overlapping pictures is also illegal).
