A Model Y driver started experiencing a medical emergency with chest pain mid-drive & called his son.

His son then remotely rerouted the car – which had FSD Supervised enabled – to the nearest hospital & let them know the vehicle was en route. ER staff were standing by on arrival.

Doctors later confirmed the quick reroute likely saved his life.

Seattle's JumpStart tax just turned five. City Hall calls it “a very successful policy.”

A new Downtown Seattle Association audit, out today via GeekWire, put Seattle next to Bellevue for the five-year checkup. The numbers don't flatter the city. /1

@RivianTrackr @RivianRuckus Maybe Rivian is sending invites to a random sample to more accurately measure their take rate. This would make delivery projections more accurate.

Pretty straightforward. All foreseen. Lots of warnings. Now there’s data to back it up.

America is unfathomably wealthy in a way that both confounds foreigners and blinds natives to how good we have it.

@DBurkland @SawyerMerritt @Tesla Yes they are aiming for hands-off and eyes-off capabilities from point to point anywhere. This is closely equivalent to FSD v14+. Rivian Gen 2 camera and inference compute is roughly equivalent to AI4.

[Mark Svendsen @marksvend]

@DBurkland @SawyerMerritt @Tesla Rivian is building an end-to-end AI model like FSD v14. Not like v11, which was hand coded rules based.

One of the worst things the progressive movement has done for society is convince large numbers of people that the success of others necessarily came at their expense. It’s bred so much resentment. And it simply isn’t true.

@StephenPunwasi Even before AI slop, Facebook managed to cause tons of apps using their SDK to crash on startup. It was also due due to malformed JSON. That was the point we decided to rip out their SDK.

i’ve owned every iphone ever made & i can safely now say this.. the new siri is a few years late but absurdly good. really good. like what it should've been from the very start.

it's genuinely conversational. it has all of the context by default. it feels native as part of the iphone hardware itself. & the dedicated camera button finally justifies its existence as an instant visual intelligence trigger. the reactive layer is basically done. & apple did an excellent job here. lots of small elements to add over time though like custom instructions perhaps.

but what’s still missing is proactive & agentic siri which is the siri that acts before you ask. that's the siri that notices, coordinates, books, filters, negotiates, & kills half the reasons you open apps in the first place.

but that's also the version that eats the app store.

I just bought a Tesla Model Y

Full Self Driving is one of the most impressive pieces of technology I’ve ever experienced.

I now wish I’d got it a year ago.

Wow, the S&P Dow Jones Indices has just officially announced that they will NOT be changing their inclusion rules to make it easier for “MegaCap” companies (such as @SpaceX) to be fast-tracked into the S&P 500.

Their reasoning:
"S&P DJI determined that exceptions to the financial viability, seasoning, and IWF requirements should not be granted solely based on market capitalization. The decision not to adopt the proposed exceptions preserves core index principles by maintaining consistent application of these key requirements. Although there may be trade-offs between strict adherence to these eligibility requirements and broad representativeness, the current methodology provides substantial market coverage and sector balance. As a result, the indices can continue to meet their stated objectives while preserving their role as representative and investable benchmarks for the U.S. equity market.

No changes will be made to the eligibility criteria including financial viability screens, seasoning period, or minimum IWF, for the S&P 500, S&P MidCap 400, or S&P SmallCap 600 as a result of the S&P Dow Jones Indices consultation on the treatment of MegaCap companies. Accordingly, there will be no changes to existing methodology for this index family."

This means that the earliest @SpaceX could be eligible to be added to the S&P 500 would now be June 2027.

The requirements that will now remain in place are:
• No changes to S&P 500 eligibility rules for mega-cap companies.
• Mega-cap companies will still need to wait 12 months after their IPO before being considered for S&P 500 inclusion.
• S&P will not waive profitability requirements for mega-cap companies. The company must have positive GAAP net income in the most recent quarter, and the sum of the most recent four consecutive quarters.
• S&P will not waive minimum public float requirements for mega-cap companies. At least 10% of a company's shares must be publicly tradable ("free float").

The S&P rejected proposals that would have:
• Reduced the IPO seasoning period from 12 months to 6 months
• Waived profitability requirements
• Waived minimum public float requirements

Gen Zers don’t remember a time when this country wasn’t horribly divided.

If your political memory starts with George W Bush and only includes Obama and Trump you probably just assume we were always this dysfunctional.

But we weren’t. We used to all hang out together and make fun of each other and stuff.

Politics just weren’t that big a deal; besides abortion our biggest arguments were over crap like marginal tax rates.

I don’t see it happening again any time soon, but I’m glad I got to at least experience it.

I hope my kid gets to one day, too.

@SDembraski @nikkharris Mine slams on the brakes at every crosswalk or intersection where a pedestrian suddenly may decide to cross. It does this even at crosswalks with no one there.

It should never emergency brake for this.
