Cars - For Car Enthusiasts

I recently (2021/2022) sold my gas cars and bought two EV's. Though I kept my two motorcycles. I've been compiling my thoughts about how it's been so far, and realized I have compiled pages and pages of notes and those notes are all over the place. Just tons of little tiny differences to massive differences in the driving experience. I'd like to share that with this community in a useful way.

I'm not exactly an EV enthusiast, I've had a very long list of enthusiast cars/bikes and when I was young I used to race both autocross and quarter mile. So this basis is where my brain is at.

So my questions for everyone here:

• What should I test/measure?
• What do you want to know?
• What data do you want to see (within reason, I'm not a data scientist)?

EDIT: You guys gave me a great list to start with. Some I'll need to start tracking my driving better so I can answer. I'll get back to you all.

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.

Been kinda fascinated by this case since watching a lot of Doug Demuro's videos from there (note that this stuff happened after Doug stopped reviewing their cars). Decided to check up and looks like Clayton is facing a long list of charges.

GM took a page out of Bethesda Softworks' release playbook with shoddy code that broke infotainment and limited fast charging to 5 kW.
