Tesla sent out an email today. Autopilot Updates We just released the latest version of Autopilot.

Automatic Emergency Braking, Forward + Side Collision Warning, and more advanced safety features are also active and standard. All Tesla vehicles have the…

"All Tesla vehicles have the hardware needed for full self-driving capability at a safety level substantially greater than that of a human driver." In the Model S configuration page, "enhanced autopilot" and "full self-driving capability" are still optional extras that together cost $8,000, so I'm not sure what they're talking about here. https://www.tesla.com/models/design

All Teslas come with the hardware needed. The $8000 enables the software.

They have the hardware but you gotta pay for that sweet sweet soft ware

I'm curious where you get the number "38 petaflops" from.

In the same sense that your dog solves differential equations when he catches a Frisbee, I suppose.

Watch this at 0.25x speed or slower to see what's going on. This is a carefully chosen environment. Every place it drives has very clear highway centerline markings. It seems to be highly dependent on those for guidance. Sometimes it can't quite identify the road edge, but the centerline provides a position reference.

The inputs seem to be road line recognition, optical flow for the road, and solid object recognition, all vision-driven. Object recognition is limited. It doesn't recognize traffic cones as obstacles, either on the road centerline or on the road edge. Nor does it seem to be aware of guard rails or bridge railings just outside the road edge. It probably can't drive around an obstacle; we never see it do that in the video.

This looks like lane following plus smart cruise control plus GPS-based route guidance. That's nice, but it's not good enough that you can go to sleep while it's driving.

"All you will need to do is get in and tell your car where to go. If you don’t say anything, the car will look at your calendar and take you there as the assumed destination or just home if nothing is on the calendar." -- that'll teach you to make sure your schedule is up-to-date!

This is not news. Current Tesla vehicles with Autopilot 2 hardware can do nowhere near this aspirational list. My AP2 Model X cannot even tell when to turn the windscreen wipers on. This is a statement of intent, and production vehicles are a long way from having software that enables this.

Do you mean the X doesn't have rain sensors, or it does but they aren't hooked up in software yet? Surely it has rain sensors, they couldn't do Autopilot using cameras behind the windscreen without them.

The human visual cortex is still far more advanced than a computer's. Maybe that will change some day, but asking about non-camera sensing equipment is a reasonable question until it does.

Sure, and it's not only cortex. Humans also know a lot about the world, and can predict things much better. There are areas in which humans are limited, however, such as reaction time, spectral sensitivity, the fact that humans can only see well in the center of where they're looking at and fake the rest of their visual field, etc. It's not at all clear to me that a human pair of eyeballs is better than 8 high qualit…

You can have a 1000 cameras and it still doesn't matter if you don't have a good computer to process the data. That is where machine learning, etc comes in. Machine learning is really starting to come into its own in last few years especially for image recognition but it still sucks compared to humans. That doesn't mean self-driving based on cameras isn't good enough but it needs to be proven and we aren't there yet.

Lidar is not "necessary" hardware. Humans drive just fine without lidar.

It's pretty obvious what the poster meant. Why doesn't tesla need lidar? Cars aren't humans, so that comparison isn't really helpful.

What the poster seems to have meant is that LIDAR is essential hardware. Which is not some universal truth, so it is they who should justify it.

You can find other figures, but many are in the petaflop range, well above what could be realistically installed in a vehicle.

So then, what about the Model S with AP1? It was produced just last year.

That isn't present tense, by saying "All Tesla vehicles produced in our factory" means today and going forward.

No, that's not what it means. It's past tense.
