The actual root cause of #2 is that, along with LiDAR, maps are also on Elon Musk’s “won’t do” list, so instead of comparing radar output to ground truth and detecting a stationary obstacle (which Waymo can do easily), Tesla tries to get by without any information about the world, and fails, badly and with sometimes fatal consequences.
- phkahler 9y agoThere is no such thing as "ground truth". Maps are for navigation, not safety. IMHO the fact that companies keep using radar and lidar indicates that their vision systems are not as good as they should be.
- surrealize 9y agoSo you have maps that record the location of stationary signs etc. and then have the car stop if it gets a radar return from a stationary object (e.g. fire truck) that's not on your map? Then when someone puts up a new sign you're slamming on the brakes until the map gets updated. Not being able to tell if a stationary object is something you're going to hit or not (like LiDAR or stereo cameras might do) is more relevant to this case than maps.
