Hi, Paul-san and Kevron-san While I do not notice it, a definition of the vehicle location information disappears in first draft spec. In the last f2f meeting, Urata-san pointed out the generic geolocation information (GPS-based) is not accurate enough. With gyro, vehicle speed, rotation angle of the wheel and so on, most of car navigation diveces have higher accuracy (within 1 or 2 meters errors in any roads of Japan) than conventional devices such as a smartphone and tablet. In the case where the OS and the device which web apps are running on support generic geolocation APIs, it becomes difficult for us to acquire the accurate positioning data easily if vehicle location information should be not available as it is. In short, we thought that geolocation information and vehicle location information are distinct APIs in accuracy. Can you restore the definition of vehicle location information in spec?
