How the figures are produced
The basis is our own analysis of the freely available OpenStreetMap data. Every Autobahn section is clipped against the state boundaries and summed by speed-limit category. “No limit recorded” means the tag is missing in the data – which is not the same as open road. A data-based analysis, not an official survey.
