I want to see that in a real dense traffic in more challenging weather conditions. Driving on well maintained empty roads in California manually is not a huge deal really.

I understand that not everything can be done at once and all that, but this again starts to look like false advertising. I'm fine with that as long as it stays in beta until it actually works.

Those roads were not empty BTW. It was literally driving around a car standing in the middle of the road.

This is cool. But I meant like pot holes. On my commute (when it was a thing) I had to strategically change lanes to avoid suspension-killing pot holes. Human can learn this stuff after running into one a couple times. I'm not sure about auto pilot.

With pure gravel road you have consistently slower speed.

Also, temporary traffic cones, temporary road markings during construction time, reroutes. Stuff that is sometimes hard to figure out as a human.

Seems to deal fine with those already. There are plans to implement pot hole avoiding https://cleantechnica.com/2020/10/03/tesla-full-self-driving-will-include-pothole-avoidance-vector-space-birds-eye-view-what-else/

The videos I've seen of "FSD" so far have been like a teenager getting behind the wheel for the first time. Yes, the beta, not people using current version wherever. Is it an uninterrupted drive from getting in to parking in these videos?

Yes, it drives a bit like a nervous teenager right now and requires assistance from time to time.  But it is still fairly impressive that this is done with vision alone.

Waymo vehicles drive more like an experienced, but safe driver.  In the US the biggest difficulty they have are unprotected left turns.  (Right turns in the UK/Aus/etc.)  In some ways, these are 'unsafe' - you just have to gun it to be able to make a gap in heavy traffic, while hoping no one in the car park you're turning into steps out.

The difference with Waymo is that Tesla can drive anywhere. Does not need high detail mapping. And Waymo technology is unrealistic for wide use because of the price of that hood on top and no realistic possibility to pre-map everything.

Tesla are still using HD maps.  It needs to know lanes for turns, traffic signals etc.    The map is 'fitted' to the vision so the car can then read where cars are and what traffic signals are set to.

The big disadvantage with Waymo is that it requires quadruple LIDAR sensors which are like $20k USD each.  Whereas Tesla is using vision alone using conventional automotive cameras (<$100/piece, RCCB CMOS sensor).

No it does not. There are no HD maps. Those are usual maps as in GPS navigator.

During the presentation, Karpathy shared a video of Tesla’s self-driving development software demonstration doing a turn and then Waymo’s self-driving prototype doing the same.

He highlighted how it looks exactly the same, but the decision making that is powering the maneuver is completely different:

Waymo and many others in the industry use high-definition maps. You have to first drive some car that pre-maps the environment, you have to have lidar with centimeter-level accuracy, and you are on rails. You know exactly how you are going to turn in an intersection, you know exactly which traffic lights are relevant to you, you where they are positioned and everything. We do not make these assumptions. For us, every single intersection we come up to, we see it for the first time. Everything has to be sold — just like what a human would do in the same situation.

Karpathy admits that this is a hard problem to solve.

However, the engineer explains that Tesla aims for a scalable self-driving system deployable in millions of cars on the road, and he argues that Tesla’s vision-based system is easier to scale:

Speaking of scalability, this is a much harder problem to solve, but when we do essentially solve this problem, there’s a possibility to beam this down to again millions of cars on the road. Whereas building out these lidar maps on the scale that we operate in with the sensing that it does require would be extremely expensive. And you can’t just build it, you have to maintain it and the change detection of this is extremely difficult.

The engineer described the map-based approach as a “non-scalable approach.”

He did say that Tesla also builds maps and use “all kinds of fusions between vision and the maps,” but their maps are not centimeter-level accurate and therefore, they can’t rely on them to navigate.

Tesla has to be able to handle any situation like it is seeing it for the first time.

OK, I suppose it's a matter of terminology there, perhaps they aren't HD maps but there is vision fitting to maps at the very least.
I do believe Tesla will crack this but like all self-driving car projects it is the long tail of "what does it do in situation <X>?"
Waymo have been comparatively slow to develop the self-driving vehicles that can only navigate in Phoenix, AZ,  in mostly good weather.  (LIDAR doesn't handle heavy rain or snow well.)

Maps are for navigation. But driving happens according to vision/radar (road, it's marking and and sign recognition).

At 16:30 you can see how it drives around debris on the road. And at the other parts of the video you can see that sometimes it takes a wrong lane on intersections.
