I have one of those and all I can say is holy shit it works. It doesn't hook into GPS, so it's not totally self driving (at least mine isn't, there's a GitHub for their software), so I still gotta pay enough attention on the freeway to know when to exit, but after I get on the freeway, left right gas brake is all taken care of. Great for sitting in stop and go on the freeway.

It's also made me think that Waymo's a) don't need lidar, and b) don't actually need the extensive mapping that the public has been lead to believe they need. They're being overly cautious, because they know people's lives are on the line here.
