Interesting, those stops don't appear to show on the heat map. The first release of the 2017 heat map had a bright route up my driveway; but there no color there now.
After the big security fuss Strava implemented some new rules in their heatmap generation. One of them was that nothing will appear on the heatmap if only one user rode in that area. That change alone eliminates the majority of driveways from heatmaps even if users don't have privacy zones.
I did a lot of gravel exploring the past few years where I've been down plenty of roads that no other Strava user has, so all those rides disappeared from the global heatmap. Its a mildly annoying since it hides plenty of unmarked trails that you might otherwise be able to discover.
