==Automatic traffic sign recognition== Cars are beginning to feature cameras with automatic [[traffic sign recognition]], beginning 2008 with the [[Opel Insignia]]. It mainly recognizes speed limits and no-overtaking areas.<ref>{{cite web |url=http://www.monstersandcritics.com/lifestyle/autos/news/article_1415817.php/Opel_Insignia_to_feature_traffic_sign_recognition_system |title=Opel Insignia to feature traffic sign recognition system |url-status=dead |archive-url=https://web.archive.org/web/20101026074935/http://www.monstersandcritics.com/lifestyle/autos/news/article_1415817.php/Opel_Insignia_to_feature_traffic_sign_recognition_system |archive-date=2010-10-26 }}</ref> It also uses GPS and a database over speed limits, which is useful in the many countries which signpost city speed limits with a city name sign, not a speed limit sign.
