You don't like that I praise Waymo but you do nothing but constantly hate on Waymo all the time. Stop it!
What does that even mean? L3 has nothing to do with "edge cases", but rather with risk/capability trade-offs. For example, the few L3 systems we have seen so far (like Audi's traffic jam assist) have a speed limitation, which is probably related to sensor scan rates and a risk assessment that Audi made.By definition, if a car knows it can't handle something, then it recognizes what it is. The problem with this is that what the car doesn't know is an edge case. It's not possible to know edge cases unless it's seen them before. That's why we've yet to see an actual L3 car. If you can solve for L3, you can solve for "L4" and "L5".
I'm not Green, and I don't know if it's true or not, but I believe what he means is that Tesla secretly wants to use lidar but can't because Musk painted them in a corner with his anti-lidar crusade, so they are now looking at high-res radar as an alternative.If not, please explain the "loss of face" that Tesla is supposedly trying to suppress data.
Lidar doesn't have to be 360 degrees. For example, Audi's L3 system has only a forward looking lidar (and it's a solid state unit, not one of those mechanically rotating things).Its one better forward looking radar unit and has absolutely nothing to do with 360 degree LIDAR cars...
Yeah, this is the least surprising development I have seen in quite some time. There is tons of room for improvement in radars.
@verygreen are you implying that the FSD visualizations that we see in the current release would "embarrass" Tesla because it somehow resembles the point clouds a radar manufacturer generates?

Here is an output from Lidar...I'm not Green, and I don't know if it's true or not, but I believe what he means is that Tesla secretly wants to use lidar but can't because Musk painted them in a corner with his anti-lidar crusade, so they are now looking at high-res radar as an alternative.
Just for clarification, can Tesla achieve L3 with this set of features by having the system programmatically determine when it needs human intervention and alerting the driver in enough time for them to resume control?
And then can they achieve L4 by having the car doing the same task as above, but also being able to find a safe place to pull over and putting on the hazards (same fallback performance of dynamic driving task as Waymo), correct?
If Green is correct, the radar that he mentions is actually a high-resolution radar, which is very different from what we currently have in the automotive sector, and has been discussed as a potential alternative to lidar:
Here Comes High-Res Car Radar
The Model Y radar is a heated unit since Launch!That's a much better (and heated apparently) radar
It can be a lot more casual then what you are suggesting. Tesla can decide to turn on L3 for below 15 mph in stop and go traffic. Once speed goes above 15 mph then Tesla starts nagging. Speed that Tesla is comfortable at for L3, can go up over time. Also L3 can be limited to starts that have favorable laws.Just for clarification, can Tesla achieve L3 with this set of features by having the system programmatically determine when it needs human intervention and alerting the driver in enough time for them to resume control?
Good point. For Tesla that can pull over, there isn't much of a difference between L3 and L4. I guess Tesla can call their traffic jam assist L4 since I suspect they will have the ability to pull over.And then can they achieve L4 by having the car doing the same task as above, but also being able to find a safe place to pull over and putting on the hazards (same fallback performance of dynamic driving task as Waymo), correct?

Tesla Model Y has a heated radar to winter-proof Autopilot
That's not the way I interpret it. He's just saying that Tesla is working on high resolution RADAR. I guess he might be implying that they're choosing high resolution RADAR over LIDAR because of Musk's past statements. There could be many other reason too.Lets summarize...
In this tweet, @verygreen is saying/implying that Tesla would be embarrassed and thus has to "save face" by hiding info of how this particular radar sees the world... because it resembles how lidar sees the world..
What is a little bit odd about Elon's anti-LIDAR position is that LIDAR is basically just better RADAR.
