No, the whole point of the original post is that a lot of users see (and use) the option, so that the app's database of personal data is full of rubbish.

I don't think the GP's scenario is realistic. A user would see that their location on the map is wrong before they even get a chance to begin navigation.

Besides, Google Maps already sometimes tells people to drive through roadblocks and locked gates and such (which it isn't aware of), so it already requires the driver to think for themselves to some extent.
