Google has a much larger and better funded team that still doesnt seem close. Karpathy is no doubt smart but google has like 10 karpathys for every one TESLA has.

The problem is these 10 karpathys have no vision, otherwise they would've joined Tesla.

Did you watch the video? Waymo is stuck using lidar, and the video explains why that's a dead-end. (Want to keep in touch about this bet? I'm maxharris9 on twitter.)

  I skimmed the video. It's doing what I expected, knocking down a goofy strawman of LIDAR-only while ignoring the obvious camera/LIDAR sensor fusion. The depth map Tesla is getting from stereoscopic vision is pretty shoddy; sensor fusion with LIDAR is the obvious solution. The reason Telsa resists this is because they want to market their cars as having all the requisite hardware and acknowledging the usefulness of LIDAR wouldn't let them market their cars that way profitably.

    Hmm, looks like Tesla actually does do sensor fusion, just not with lidar: https://news.ycombinator.com/item?id=19803817 https://news.ycombinator.com/item?id=19803817 I also think that being so cynical about Tesla's motives is pretty short-sighted from an investment perspective. In the long-term, they don't win if they don't get this right.

      Their radar/ultrasound has awful angular resolution. That's where LIDAR excels. This is why Telsa cars run into trucks parked across the street. Their stereoscopic depth map is shoddy and the radar or ultrasound has awful angular resolution that can't tell the difference between an object parked next to the street and one parked in the middle of the street. > "In the long-term, they don't win if they don't get this right." They've been claiming they're on the cusp of getting it right in the short-term for years. So far, my cynicism has served me well.
