Map display subject to visible transport layers only.

Currently, the map display will scale to show the furthest extent of your recorded travel. When you turn off a travel mode (e.g. Airplane), or restrict the time extent to be displayed, the scaling does not change, even when reloading the page (with the previous visibility settings). This can lead to a map that is uncomfortably zoomed out due to an invisible flight, or an old trip, which is not shown on a map. The map should scale to the visible trips/other recorded things only, and not to all of them. This would lead to a map that is correctly zoomed all of the time, instead of a single trip to somewhere far away/far in the past that has been filtered out that isn't visible changing the centre and zoom level of the map.
