In Japan, the blue line can be drawn in the intended location based on the location information obtained from GNSS (GPS).
Therefore, you can draw the street view of the newly created road at the correct coordinates even if the road is not yet drawn on the map, as shown below.

After that, the road on Google Maps Web was drawn in the right place,
Further after that, the official Street View was shot on the new road.

It seems that some official SVs of old bridges have broken connections and coordinates due to the removal of road drawings.

However, in many countries other than Japan, the process has changed from two years ago to snap to existing roads depicted on the nearby Google Maps Web.
Even if you take a picture of the street view of the promenade in the park next to the motorway, the blue line of the street view of the promenade will be drawn over the motorway.
I’ve seen an answer from the Street View team that it decided that “the location information the user is getting is inaccurate, so the road information on the map is correct”.
Fortunately, the reason why the unfortunate snap processing is not performed in Japan is that the map of Japan is inaccurate.
It seems that the contract between Zenrin, a major map company, and google expired in March 2019.
As a result, Google is no longer able to use an accurate map of Zenrin.
It became necessary for Google to infer information on Japanese roads, residential areas, mountains and rivers from aerial photographs, and to infer roads from the movement records of Android users’ location information.
And Google Maps in Japan had various problems for a while after that.
For example, the plateau that looked black in the shadow of the mountains is displayed as a lake, the parking lot of a shopping mall where many cars pass is displayed as if it is a public road, many country roads have been removed from the map because no car running. etc.
As such, maps of Japan are still inaccurate, so I think they set a high degree of trust in information from users.
This symptom is not dependent on the user’s account.
I think it’s an attribute of the map location itself.
As proof of that, the Street View I shot in the U.K. and blue-lined shows the symptom of being snapped onto an existing road nearby.
The coordinates of each photo seem to be in the correct position.
However, the blue line drawn is snapped to a nearby road and is drawn in the wrong place.
If I click on the correct coordinates of the photo on Maps Web, I can correctly display the Street View that exists at those coordinates.
Therefore, I feel that only the drawing process of the blue line is in a disappointing state.

From the above experiment, if a road is drawn on Google Maps within 50ft (15m), you can imagine that the blue line will be snapped on that road.
In Japan, a blue line is currently drawn in a place that almost follows the GNSS data (GPS data) I acquired.
The coordinates of the photo are GPS data obtained by SV App at the time of the shooting, so the information may be slightly inaccurate, but the blue line is drawn in a place that is almost in line with the actual situation.

When the coordinates of the photos are close, there is no difference whether it is a user post or official, and the latest photo is often displayed.
They have a time machine function that allows you to move between photos at different times.

This article is a rewrite of an article I posted on the SV Discussion Board in the past, using current information.
The wisdom of users regarding SVs, including the articles written below, has been deleted the whole SV Discussion board along with the compilation of past wisdom due to the work of SV moderators who aimed to erase the entire history of poor support systems which continued for 3 or more years.
SV moderators are now called SV Trusted Help.
