Tesla's Full Self-Driving Beta Rolls Out To Rave Reviews

Rei writes: "Oh, it's going dude!" "But there's no lanes -- there's cars on the side of the road!" "DUDE, it's navigating through it ALL, bro!" ... "It paused to look DUDE!" "There's NO LANES! Elon, you madman!" Such was one of the many reaction videos to come out overnight as Tesla released a major upgrade of Autopilot to a limited public beta. Complete with a new LIDAR-like visualization system, the car now provides a detailed display of how it perceives the world as it dodges parked cars, takes unprotected left turns with cross traffic and pedestrians, etc. No issues have been reported thus far, although one driver aborted after a roundabout due to a panicked passenger who didn't like how it exited into a lane with parked cars ahead (though the screen showed that it planned to change lanes to go around them).The new version is the result of a long-running "4D" rewrite at Tesla, to overcome local maxima in earlier versions. Instead of processing each camera individually as a static series of frames, the neural net now processes a unified stitch of inputs over time, allowing context to persist between cameras and between frames. This in particular enhances parallax processing of depth input, both in terms of parallax between camera viewpoints and parallax between vehicle positions. If the public beta goes well, Elon is hopeful that Tesla will be able to roll out the new version broadly by the end of the year.
