11 February 2015. This article from BBC describes the current (lack of) legislation in countries worldwide. The UK government promises a full review of current legislation by the summer of 2017. The US was the first country to introduce legislation to permit testing of automated vehicles. Four US states have done so but 15 have rejected bills related to automated driving. In Europe, only Germany and Sweden have reviewed their legislation in this area.
