Self-drivable cars hade been around for years. What's different about the Google Prius versions is that they look almost practical, if you squint just a little bit, just minimized the sensors a little bit more it could even fit within a car's stylish exterior. In contrast, some of the past versions were very slow driving and had a truck's worth of equipment in them.
I really think this is a false comparison (to other corporate future videos). Google may release a product that fails to gain adoption, but they will release something.
BTW, go search youtube for AT&T's "You Will" campaign with Tom Selleck. They got a lot of stuff right.
