I know Rooster Teeth isn't perfectly game related per se, but their machinimas and miniseries using game assets were transformative for many of us in the gaming community I believe. So I think it fits.

Under structural-only DP loading, a certain amount of deflection is allowed, and a certain amount of post-loading set displacement (permanent deformation) is allowed. Under the DP (design pressure) system, DP ratings are defined differently for structural, water leakage, and air leakage tests. This is a structural only test, so it is not mandatory to maintain a water or airtight seal during or after the load is performed, it simply must not break either the frame, the door, or the glass.

I'm not sure if this unit was a pass or a fail. It at least didn't break.

This two-panel patio door unit has an astragal on the inactive (non-handled) panel with shoot bolts into the head and sill. The active (handled) panel has no shoot bolts in this design, and acts more like a traditional door system.

I believe this was a DP50 structural test rating, equivalent to a 200mph wind. DP is gradually being replaced by the PG rating system which also includes air and water leakage during and after loading in a single unified test definition.

From my previous comment, it looks like NHTSA is moving faster than I predicted. We're now at step 1, with this Advance Notice of Proposed Rulemaking.

Most of this notice seems to be a report on why 'impaired driving' is bad. I see alcohol, cannabis, mobile phone use, drowsiness...etc.

Due to technology immaturity and a lack of testing protocols, drugged driving is not being considered in this advance notice of proposed rulemaking.

Makes sense.

There is no clear and consistent engineering or industry definition of ‘‘impairment.’’

Yep, another unclear request by Congress.

NHTSA believes that Congress did not intend to limit NHTSA’s efforts under BIL to alcohol impairment.

Okay, that's fair.

Camera-based-systems, however, are increasingly feasible and common in vehicles.

Uh-oh...

The Safety Act also contains a ‘‘make inoperative’’ provision, which prohibits certain entities from knowingly modifying or deactivating any part of a device or element of design installed in or on a motor vehicle in compliance with an applicable FMVSS. Those entities include vehicle manufacturers, distributors, dealers, rental companies, and repair businesses. Notably, the make inoperative prohibition does not apply to individual vehicle owners. While NHTSA encourages individual vehicle owners not to degrade the safety of their vehicles or equipment by removing, modifying, or deactivating a safety system, the Safety Act does not prohibit them from doing so. This creates a potential source of issues for solutions that lack consumer acceptance, since individual owners would not be prohibited by Federal law from removing or modifying those systems (i.e., using defeat mechanisms).

Note that "make inoperative" does not apply to a "kill switch" in this case. NHTSA uses the term to mean "disabling required safety devices". For example, as an individual vehicle owner, it's perfectly legal for you to remove the seatbelts from your car, despite Federal requirements. But it's illegal for the entities listed above to do it. (This example doesn't extend to state regulations. It's legal for you to remove your seatbelts, but may still be illegal to drive a car without them.)

There's a short 'discussion' here regarding how to passively detect impaired driving, noting the difficulties of creating such a system. Followed by a note that basically says if they can't do it within 10 years, NHTSA can give up and not do it, as stated in the Infrastructure law.

There's a long section on how to detect various types of impairment, current methods of preventing impaired driving, etc. An interesting section about detecting blood-alcohol level using infrared sensors embedded in the steering wheel. Body posture sensors can be used to detect driver distraction.

This is followed by a brief overview of the technologies NHTSA is considering:

Camera-Based Driver Monitoring Sensors

Hands-On-Wheel Sensors

Lane Departure and Steering Sensors

Speed/Braking Sensors

Time-Based Sensors

Physiological Sensors

On page 850 (21 of the PDF), NHTSA asks for feedback to several questions. There are a few pages of relevant issues, so I won't cover them here. If you wish, you can go here to leave a comment. Please don't leave irrelevant garbage like "I oppose this on the grounds of my Constitutional rights..." While applicable in this situation, it's irrelevant to NHTSA, and commenting like that will just waste everybody's time. There's a section on page 855 (26 of the PDF) about Privacy and Security.

That's that. Let me know I can answer any of your questions. I'll try to come back to this post throughout the day and see what's happening. But, I do not work for NHTSA, so can't remark on agency thought process.
