by governments on a fairly regular basis. It is not known if governments use this data for purposes other than the placement of speed cameras, such as to improve the road network, introduce traffic lights or find accident hotspots. Open Map Community Controversies In 2012, Tomtom made aggressive remarks on reliability of OpenStreetMap, an open-source mapping and routing competitor. Contributors disputed that out of 100,000 attacks by Google contractors only about a dozen were 'hit' and they were swiftly reverted by community. Evaluation by researchers found that in Germany the difference was 9%. OSM in fact exceeded the proprietary dataset by 27%. Since 2012, TomTom has worked alongside OpenStreetMap with organised editing activities, and have been one of many sponsors of The State of The Map Conference for the OpenStreetMap community. Competition TomTom's main retail car satellite navigation competitors are MiTAC (Navman and Magellan Navigation) and Garmin. TomTom's main autonomous driving HD maps competitor is Here, which is owned by a consortium of German automotive companies including Audi, BMW, and Daimler.
