@wholemars Do you think other safety systems in the car (obstacle aware acceleration, AEB) could have helped? Or do they only work in narrow situations?

Luckily there is an NHTSA investigation so we'll hopefully learn the facts of how the system behaved.

[Ryan Ziolko 🚀 @MediumFidelity]

@TheCTStud @aelluswamy @SawyerMerritt @ChuckCook @Tesla_AI Pedal confusion is the most likely culprit. It's possible the issue was compound by a loose object in near the pedal (water bottle, etc). I don't think it's a fault with the vehicle.

Let's hit up Occam to borrow his razor.

@grantbelden @wholemars We need more data from Tesla, but I'd put this at the top of likely scenarios. A quick intervention was perceived to be needed, and then pedal confusion.

[Ryan Ziolko 🚀 @MediumFidelity]

@wholemars @aelluswamy shared the maximum speed, which was presumably right before the impact if the car was accelerating. A timeline of the telemetry overlayed on a map would be helpful to understand what happened.

I'm curious about what led to the driver thinking pedal input was needed.

@wholemars Did Tesla refute Autopilot being active?

[Ryan Ziolko 🚀 @MediumFidelity]

@aelluswamy @ChuckCook @Tesla_AI Are obstacle aware acceleration or automatic emergency braking supposed kick in at all in these cases?

[Ryan Ziolko 🚀 @MediumFidelity]

@aelluswamy @Tesla @ChuckCook @Tesla_AI Was Autopilot active? It sounds like braking was overridden by the accelerator, but was AP still in control of steering?

Did something go wrong prior to the acceleration that would have caused the driver to brake hard (while experiencing pedal confusion)?

[Ryan Ziolko 🚀 @MediumFidelity]

@TheCTStud @aelluswamy @SawyerMerritt @ChuckCook @Tesla_AI The tricky part here is that Autopilot *was* active, so neither the statement the driver nor the headline were inaccurate. The devil is in the details of how the accelerator was pushed (which came to light later).

[Ryan Ziolko 🚀 @MediumFidelity]

@SawyerMerritt @aelluswamy @elonmusk @kylaschwaberow The headline is accurate (Tesla isn’t refuting that AP was active). The story should be updated to include the new information about the accelerator being pressed.

A map view with telemetry overlayed would make it easier to understand how the system behaved.

@JonBbC_TechGeek Is your Model 3 in for service? What's wrong?

[Ryan Ziolko 🚀 @MediumFidelity]

@SawyerMerritt @SpaceX The disappointing part is that SpaceX can’t come up with a way to use the compute to make something that makes more than just rental fees.

[Ryan Ziolko 🚀 @MediumFidelity]

@wholemars It’s odd that selling access makes sense SpaceX (xAI) and/or Tesla. As an outsider, I’ve had the general feeling that xAI had a lot of money to spend, and became GPU rich without as much on the SW side to utilize it.

Give Tesla a deal a train that V14-lite for HW3 folks. 🙃

[Ryan Ziolko 🚀 @MediumFidelity]

@FredLambert Is the claim that the driver did have pedal confusion, but figured it out and tried to brake in the last 6 seconds?

[Ryan Ziolko 🚀 @MediumFidelity]

@FredLambert It’s curious, but are you saying cellular daughter card is the persistent storage in the system?

The clip showing the wild ride is longer than 6 seconds, and there was telemetry showing the accelerator was used for some of it?

[Ryan Ziolko 🚀 @MediumFidelity]

@luigifcruz If you want to be *really* cool, get an ankle holster for it to wear on hikes. 🤓

[Ryan Ziolko 🚀 @MediumFidelity]

@Tesla I’d love to! Is it available on HW3 cars that purchased FSD years ago?

[Ryan Ziolko 🚀 @MediumFidelity]

@wxbits1 Neat. What does the antenna setup look like?

[Ryan Ziolko 🚀 @MediumFidelity]

@Acquired_Savant @SawyerMerritt @Tesla Nothing to see here, this is just the car finding the charger with Bluetooth and then UWB for fine guidance.

I wonder why they didn’t use cameras. I guess if there is UWB hardware for passive entry. 🤷‍♂️

[Ryan Ziolko 🚀 @MediumFidelity]

@SawyerMerritt @Tesla This is an outdoor AirTag, and just UWB for positioning. Pretty cheap/easy these days.

Surprised they can do it with just cameras 🙃 Maybe they can get the accuracy they need with vision.

I think self docking robot vacuums pulled this off a while ago.

[Ryan Ziolko 🚀 @MediumFidelity]

@SawyerMerritt Which ones have 4680's? Really curious to see if Tesla has improved the stinker of charge curve from the original 4680 Model Y.
