"All Tesla vehicles produced in our factory, including Model 3, have the hardware needed for full self-driving capability at a safety level substantially greater than that of a human driver." That claim is strong and false. What about Roadster and the old Model S with the old AP1 hardware?

I would read it as "All Tesla vehicles CURRENTLY produced...". It's a reassurance that every new car you buy now will have the capabilities.

"All Tesla vehicles produced in our factory" is present perfect tense, implying an event that happened at an unspecified time in the past and continues to the present. You would have to add "ever" to include all vehicles ever produced.

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.

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

Humans have the computation equivalent of 38 petaflops of processing power. Does a Tesla vehicle? If you seriously want to play the inane game of "well if a human doesn't have it then a Tesla doesn't need it" then let's play that game and talk about the things humans have that the Tesla lacks. What's interesting about human's vision system is that the human eyeball is, relatively speaking, poor. We have digital camer…

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

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 quality, wide spectrum cameras feeding into the system at once.

That said, I think it's disingenuous of Tesla to call their system "autopilot" or imply autonomy of any kind when talking about their system. I will call something autopilot when it can drive me from door to door without me touching the wheel, in less than friendly weather conditions. Not drive in a straight line where it never rains.

You don't need 38 petaflops to drive a car. We are wasting our minds driving. Driving doesn't need creativity, it needs the 360 degrees of awareness without any lapse in concentration and the ability to react in milliseconds.

Tesla sent out an email today. Autopilot Updates We just released the latest version of Autopilot. You can now experience Enhanced Autopilot features including Traffic-Aware Cruise Control, Autosteer, Auto Lane Change, Parallel + Perpendicular Autopark, and Summon. 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

As i understand it, the newer ones use a machine learning based approach and different hardware than the old ones. Does this mean tesla is actively working in parallel to develop two completely different self driving car softwares, one built on ML and one around a more traditional heuristic approach?

Will I get a DUI if I'm drunk and my car drives me home? Say I'm in the back seat.

Yes. You can get a DUI if you're in a car that's either turned on or has the keys in the ignition, even if it's parked.

Teslas don't have ignitions. And what defines "turned on" for an electric vehicle?

Humans also lose focus, fall asleep and get tired.

Teslas have multiple radars for judging distance and multiple cameras that are used for stereo disparity. Also human 38 teraflops is not the same as nvidia teraflops.

I am not saying teslas are better than humans, I'm just saying teslas can drive on I5 highway from Vancouver to Mexico better than I can.

Also Lidars are really really expensive, I applaud Tesla and commaai for breaking major ground just with cameras. Convolutional neural nets have being doing phenomenal things in the past few years.

I would guess that if you gave the command to drive home, you would be seen as the operator of the vehicle and would probably receive a DUI. If there is an emergency and the automobile needs human intervention, then you would be responsible.

Yeah. When I was in J-school, I covered a court case where a man was convicted of DUI when the cops found him asleep in the back seat of a car with the engine running. He knew he was too drunk to drive and decided to sleep it off in the back. It was a cold winter night so he turned on the engine to run the heater.

He got convicted because being inside the vehicle with the engine running met the definition of "operating" it, and nobody wanted to start down that slippery slope.

I would peg the human brain at closer to 1 flop. That's about how many floating point operations I can do in a second, and only very simple ones.
