FSD with current great? Not possible.

[lynnpt2001]

If you study the cameras and sensors on current teslas it would appear that Fsd is not possible. Think about the car stopping then having to pull out onto a highway where the speed is excess of 55 mph, the car cannot see to the left and right far enough to make the decision and time the maneuver. Something else needs to come into play for that one task to occur. Watch the camera recordings from all cameras you will understand. The radar and side sensors cannot detect that far.

To be fair, this scenario is pretty hard even for human drivers. And humans only have two cameras.

Use Mad Max mode.

Would love to read your paper where you present your proof that it’s not possible.

Fwiw, here the sensor suite:

Not trying to stir up anything, was just in that scenario yesterday, made me think if the car was in that situation on its own how would this be possible. Would you want to be sitting in the back while your car is pulling out onto a highway under those circumstances? It's simply a logical conclusion, nothing more. Just wanted really to gain other perspectives. To be clear Tesla is clearly the best car in the world for so many reasons but this scenario may be too much of a challenge based on current hardware.

No insight into the OP's question, but did want to comment on your comment. Isn't part of the difference that while humans only have two cameras, there is no limit as to which direction those two cameras look? Vs cameras in a Tesla are limited to the intended/installed direction? Just a thought.

The gap between the wide forward and rearward cameras sure seems a bit scary for crossing traffic. I wonder how they're dealing withat?

Side cameras.

 

[paaltio]

Side cameras.

That's what I mean, the about 20-degree gap between the side cameras and the front cameras that is only filled by the ultrasonics in that diagram. Is it not accurate then?

Well our necks aren't locked, so we can turn our two "cameras" around on a swivel, which is full 360 view.

Ultrasonic is the small yellow area around the car. The light green is the forward looking side camera.

There's a lot less than 360 degree view that a human gets. First, there are folks with physical issues that can't pivot 360 degrees, and even you head, by itself, can only get about 300 degrees. To get directly behind you requires shifting the body, something that most folks are hesitant to do when in a car.

But even then, there are a number of barriers in a car that you can't see through, the so called "blind spots" Tesla can actually see the blind spots better than you can.

But it looks, for this particular issue, that the forward looking side cameras cover 240 feet.

Look at heltok's post.
Now do the math.

 

[commasign]

The camera coverage is full 360 degrees. In fact, there’s overlap and redundancy such that most angles are covered by at least two cameras. Unlike humans, there’s a view of all angles at all times.

The gap between the main forward camera and the forward looking side cameras is much less than 20 degrees. It's a tiny sliver of a gap.

There’s no gap. Look at the overlap between the forward looking side cameras and the wide forward camera.

Right. I was looking beyond 60 meters. Between 60 and 80 meters, beyond the range of the wide camera, there is a very small gap.

Ah, ok. Yeah that makes sense. Wonder if that’s related to the camera’s resolution. Elon did say that moving to HW3 will allow all cameras to operate at full resolution and 60fps whereas current HW2+ some of the cameras would have to operate at lower resolutions and frame rates.

I think you raised a valid question. Here are some thoughts though:

1. What would you do as a driver, if you had an intersection that was so difficult and scary that you would be concerned for your and your passengers' safety? I think you would avoid it! That's one simple solution. The car could take into account its limitations and reroute accordingly.

2. More importantly, I think as autonomous driving becomes a reality, municipalities will have to help the process by making road signs, lane markings and intersections more autonomous car-friendly. It's already happening!

Can you point to where this is already happening? I hope it happens soon, but haven't seen any indication of this in the Charlotte or Atlanta areas...
