J. Steven York RESISTS

US hardware standards are INSANE.
Working on a prop for my action-figure photo comic, "Minions at Work," and I want to attach some decorative lamp finials upside down as legs for a piece of furniture. Go to store, get some screws. Easy, right? A standard 1/4" screw is 20 pitch thread. But a lamp finial is 1/4" 27 pitch, for reasons that probably made sense to Tommy Edison. Can't find screws like I want, even online. (cont.)

A decorative brass colored lamp finial (the knob that holds a lamp shade on) and a not-quite compatible M6 bolt because it's the closest thing I can find that even vaguely works thanks to antiquated US hardware standards.

What is a Level 3-capable vehicle?

Put simply, per the #SAE #J3016 standard (which is not safety standard), this is a vehicle that is capable (by definition, not necessarily practically) of detecting a certain amount of failures to the Dynamic Driving Task (DDT) within a certain Operational Design Domain (ODD).

With some exceptions, the human driver can (theoretically) remain inattentive to the performance of the DDT until the automated system demands that they regain operational control.

While one could go to the official #SAE website and download the #J3016 for free... I would highly recommend Professor Phil Koopman's "User Guide" which draws only from the standard and attempts to explain the dry technical language within in a more approachable way.

Professor Koopman does not at all pervert the standard language and had taken great pains to not do so, unlike many individuals and organizations scattered about on the Internet.

Ok.

What are these "levels" everyone is talking about?

The original source of the levels is a standard published by the #SAE with the designation of #J3016.

The standard is entitled "Taxonomy and Definitions for Terms Related to Driving Automation Systems for On-Road Motor Vehicles".

Note that the title does not include the term "autonomy" which is found no where in the actual standard.

If you want to utilize "the levels" in conversation, this is the only place you should be drawing from.

The chart presented below claims that it is sourced from the #SAE and the #NHTSA, but...

**THE CHART IS WRONG!**

I took this from a "Tesla Twitter" exchange.

#Musk has staked much of #Tesla's future on the near-term success of their #FSDBeta program (however "success" is even defined)... so, naturally, there has always been an impulse on Twitter to "stretch" the capabilities of Autopilot and FSD Beta.

Let's take this apart because there are important public safety ramifications here.

A chart titled "Five Levels of Vehicle Autonomy". There are five columns on this chart - labeled from "Level 0" on the far left and each level is incremented by 1 until it arrives as "Level 5" on the far right. Underneath each level designation, there is text that attempts to describe each level. It should be noted that this chart is wrong in how it describes the capabilities of each level. The levels are described as follows: Level 0: No automation: the driver is in complete control of the vehicle at all times. Level 1: Driver assistance: the vehicle can assist the driver or take control of either the vehicle's speed, through cruise control, or its lane position, through lane guidance. Level 2: Occasional self-driving: the vehicle can take control of both the vehicle's speed and lane position in some situations, for example on limited-access freeways. Level 3: Limited self-driving: the vehicle is in full control in some situations, monitors the road and traffic, and will inform the driver when he or she must take control. Level 4: Full self-driving under certain conditions: the vehicle is in full control for the entire trip in these conditions, such as urban ride-sharing. Level 5: Full self-driving under all conditions: the vehicle can operate without a human driver or occupants.
