You might not have heard of Wheego and Valeo before, but they must be doing something right when it comes to self-driving vehicles. California has given them permission to test one autonomous car each on its roads, according to The Wall Street Journal. The state recently approved a bill that allows fully autonomous car testing -- in other words, test vehicles will be allowed to drive around without a human operator. Wheego and Valeo, however, will have to work their way up to that point. Their cars still need to be operated by up to four human drivers.
