There's a lot of attention to self-driving cars in the US, but it seems worth noting that similar work is being done in other places. There's a recent test of a Dutch self-driving truck reported here and South Australia is discussing making self-driving cars legal there.
Actually Audi and Mercedes (German) also have very far advanced self-driving programs. In January 2015 an Audi drove itself from the middle of Palo Alto, California, to the convention center in the middle of Las Vegas, Nevada, a distance of about 870 km. Reporters took turns sitting behind the wheel doing nothing.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
