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?
