@geerlingguy It would be nice to share your lawn mower with your neighbors, we'd really cut down on the number of lawn mowers out there. Same with snow blowers. Actually, is this a thing?

@SMRdeka @midwestern_ope I thought it was flux capacitor...

@khaphora @cibi_c @yunta_tsai @wholemars Just because Telsa wasn’t able to figure out sensor fusion (with radar) doesn’t mean it’s not possible/valuable.

I get that Telsa is aiming for a low cost solution, but there are other ways that aren’t inherently wrong. 🤷‍♂️

[Ryan Ziolko 🚀 @MediumFidelity]

@cibi_c @yunta_tsai @wholemars You wouldn't *only* use lidar, but fuse it with other data sources, just like our brains fuse together our senses.

They are absolutely cases where lidar helps, along with others where it doesn't. It's a tool in a toolbox.

@SantoroSystems What’s the word on the suspension?

Where I live, it wouldn’t be a very long nap. <bump>

There would also be some challenges in seatbelt design if you wanted to get closer to a comfortable sleeping position.

@SantoroSystems @kurt_niles Even in "Standard" V14.1 L will speed (35 MPH in a 25 MPH zone) if the person in front of you speeds. They need to work on the "keep up with traffic" rules for residential roads.

There needs to be a more elegant/communicative way to say "slow down!" than changing profiles.

@wholemars I guess, but for me I consistently parks on the wrong side, and as I backup and pull in, it trigger the HomeLink garage door as the car is still going in the garage.

It hits (sometimes literally) so many issues parking, people must really go out of their way for the streak.

[Ryan Ziolko 🚀 @MediumFidelity]

@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 @teslasi 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.

[Ryan Ziolko 🚀 @MediumFidelity]

@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.

[Ryan Ziolko 🚀 @MediumFidelity]

@wholemars Did Tesla refute Autopilot being active?

[Ryan Ziolko 🚀 @MediumFidelity]

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

[Ryan Ziolko 🚀 @MediumFidelity]

@aelluswamy @Tesla @ChuckCook @teslasi 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 @teslasi 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.

[Ryan Ziolko 🚀 @MediumFidelity]

@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?
