What this site does not claim

The curve counts measure an OpenStreetMap polyline, which is a volunteer trace of a road rather than a survey of one.
The demand map says where a road asks the most of a rider. It is not a record of where anyone has crashed; no such record is published for these roads.
The air model never produced a daily mean above 99.4 µg/m³ in 15,050 point-days. Ground stations have recorded far higher. Read the season from it, not the ceiling.
Harvested places are what volunteers mapped on a date. An absence is an absence from the dataset.
Prices, opening hours and business details are not published here unless a named source was checked. Where they were not, the page says so.
