There is a very good article about then safety while hitchhiking from Bernd Wechner: http://bernd.wechner.info/Hitchhiking/Suite101/Article/?22 Maybe we should link it here. Unfortunately I couldn't find the report from the BKA that Bernds article is based on. Anyone has a copy? --MrTweek 13:32, 22 June 2007 (CEST)
No copy here. That study is still available in some specialized libraries in Germany and Belgium. It's nice enough to know it exists, owning does not really make my life better.
