It is a very common practice, because otherwise these apps would fail
badly in dense urban areas, where the GPS accuracy is simple not enough
to decide which road you're on.

There *has* to be some logic in a vehicle navigation app, which decides
"well, he drove on the highway the whole time, so he likely still is on
the highway and did not teleport to the city street right beside it,
although the current GPS coordinates suggest the latter".

But of course, there is no rule without exceptions. Some developer might
have come up with a different, ingenious idea. And some software
companies might just don't care about user experience, as long as the ad
revenue is coming in.

What you say makes a lot of sense; otherwise we'd be jumping from road to
road when they closely parallel each other (and we'd often end up in the
nearby lakes and housing developments too!).

I'd love for _more_ apps to take into account those tracking abilities.
For example, for my default mock location spoofer, I use this app.
<https://play.google.com/store/apps/details?id=com.lexa.fakegps>

While I like that Lexa will randomly move x distance in y time, I would love
if it had the ability to _track_ along a roadway like the navigation apps
do.

Tracking along a given road would be a more accurate spoofing than just
random movements of twenty feet westward every thirty seconds or so.

AFAIK, at least on Android, we can not lock updates on one app. Maybe
download the package separately, and store it? If it gets uninstalled,
install again from backup. Is that practical?

Thanks.
