SpaceX scraps Florida Starship Mk2 prototype
SpaceX has scrapped the lone Starship prototype built in Florida in 2019, surprising very few.
Beginning a few months after work began on Starship Mk1 at SpaceX’s South Texas production facilities, a separate team in Cocoa, Florida was tasked with building a similar Starship Mk2 prototype. Not much is known about Mk2 relative to its much more publicized sibling but unofficial photos and videos taken over the course of 2019 suggested that SpaceX had effectively completed most of Starship Mk2 by the end of last year. However, built dozens of miles and several waterways away from a practical test facility, actually testing a Starship prototype assembled at SpaceX’s Cocoa facilities was always going to be an uphill battle.
To warrant the cost and effort that would be required to transport something as large as a vertical Starship from Cocoa, Florida to Cape Canaveral, Mk2 would have to be able offer something invaluable during testing. Now eight months after Starship Mk1 was destroyed during one of its first real tests, that was sadly not the case and SpaceX has chosen the simplest route forward – scrapping Mk2 where it sits.
In November 2019, SpaceX installed Starship Mk1 on a test stand in Boca Chica, Texas and began a series of tests. The ship passed an initial ambient temperature pressure test on the 18th but failed spectacularly during its first cryogenic proof test, said by SpaceX to have “pressurize[d] systems to the max.” Excluding Starhopper, Starship Mk1 was about as rough of a prototype as SpaceX could have feasibly built and the fact that it survived any length of time under cryogenic loads and pressures was fairly impressive.
Welded together almost entirely out in elements on the South Texas Gulf coast, the total success of Starship Mk1 (and its similar Mk2 sibling) would have flown in the face of almost every single tenet of modern aerospace production. As noted in a Teslarati article describing the Starship’s demise, the Mk1 production apparatus left plenty of room for improvement.
“[Videos of the failure implicated] the weld connecting the LOX dome to the cylindrical body of Starship’s LOX tank, pointing to a bad weld joint as the likeliest source of the failure. Although that hardware failure is unfortunate, Mk1’s loss will hopefully guide improvements in Starship’s design and manufacturing procedures.”

That is precisely what SpaceX did – and was likely already doing – in response to Mk1’s failure. Just two months later, SpaceX successfully tested a steel Starship tank built in upgraded facilities with upgraded methods and reached pressures of 7.1 bar (~103 psi) before failing – likely a 50% improvement or better relative to Mk1. A second tank completed weeks later in late January 2020 reached 7.5 bar, sprung a leak, was repaired, and ultimately soared to 8.5 bar (~125 psi) before failing. Per CEO Elon Musk, that would technically be enough for a Starship to launch humans into orbit with an industry-standard ~40% safety factor.
Finally, SpaceX recently proved that a full-scale, two-tank Starship prototype built with the same methods and facilities as those test tanks could achieve the same results, completing a ~7.5 bar (~110 psi) cryogenic proof test with Starship SN4 on May 10th.
Long story short, the methods SpaceX used to build Starship Mk1 and Mk2 were already proven redundant more than six months ago and buried even deeper in May 2020. Aside from serving as a museum piece, Starship Mk2’s fate was sealed – the only real question was how and when it would be scrapped. For now, SpaceX’s Starship program will be almost exclusively stationed in South Texas, where it appears to be in good hands. Starship SN5 is currently expected to attempt its first wet dress rehearsal (WDR) and static fire tests no earlier than July 17th (today) at 8 am CDT (13:00 UTC).

GM CEO Mary Barra says she told Biden to give Tesla and Musk EV credit
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”
General Motors CEO Mary Barra said in a new interview on Wednesday that she told President Joe Biden to credit Tesla and its CEO, Elon Musk, for the widespread electric vehicle transition.
She said she told Biden this after the former President credited her and GM for leading EV efforts in the United States.
During an interview at the New York Times Dealbook Summit with Andrew Ross Sorkin, Barra said she told Biden that crediting her was essentially a mistake, and that Musk and Tesla should have been explicitly mentioned (via Business Insider):
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”
GM CEO Mary Barra said to Andrew Sorkin at the New York Times Dealbook Summit that she pulled President Biden aside and said Tesla CEO @elonmusk deserved the credit for EVs:

Back in 2021, President Biden visited GM’s “Factory Zero” plant in Detroit, which was the centerpiece of the company’s massive transition to EVs. The former President went on to discuss the EV industry, and claimed that GM and Barra were the true leaders who caused the change:
“In the auto industry, Detroit is leading the world in electric vehicles. You know how critical it is? Mary, I remember talking to you way back in January about the need for America to lead in electric vehicles. I can remember your dramatic announcement that by 2035, GM would be 100% electric. You changed the whole story, Mary. You did, Mary. You electrified the entire automotive industry. I’m serious. You led, and it matters.”
People were baffled by the President’s decision to highlight GM and Barra, and not Tesla and Musk, who truly started the transition to EVs. GM, Ford, and many other companies only followed in the footsteps of Tesla after it started to take market share from them.

Musk would eventually go on to talk about Biden’s words later on:
“They have so much power over the White House that they can exclude Tesla from an EV Summit. And, in case the first thing, in case that wasn’t enough, then you have President Biden with Mary Barra at a subsequent event, congratulating Mary for having led the EV revolution.”
In Q4 2021, which was shortly after Biden’s comments, Tesla delivered 300,000 EVs. GM delivered just 26.

Tesla Full Self-Driving shows confident navigation in heavy snow
So far, from what we’ve seen, snow has not been a huge issue for the most recent Full Self-Driving release. It seems to be acting confidently and handling even snow-covered roads with relative ease.
Tesla Full Self-Driving is getting its first taste of Winter weather for late 2025, as snow is starting to fall all across the United States.
The suite has been vastly improved after Tesla released v14 to many owners with capable hardware, and driving performance, along with overall behavior, has really been something to admire. This is by far the best version of FSD Tesla has ever released, and although there are a handful of regressions with each subsequent release, they are usually cleared up within a week or two.
Tesla is releasing a modified version of FSD v14 for Hardware 3 owners: here’s when
However, adverse weather conditions are something that Tesla will have to confront, as heavy rain, snow, and other interesting situations are bound to occur. In order for the vehicles to be fully autonomous, they will have to go through these scenarios safely and accurately.
One big issue I’ve had, especially in heavy rain, is that the camera vision might be obstructed, which will display messages that certain features’ performance might be degraded.

I found the steepest, unplowed hill in my area and tested the following:
• FSD 14.2.1 on summer tires
• FSD 14.2.1 on winter tires
• Manual drivingBut I think the most impressive part was how FSD went DOWN the hill. FSD in the snow is sublime $TSLA pic.twitter.com/YMcN7Br3PU

Well.. I couldn’t let the boys have all the fun!
Threw the GoPro up and decided to FSD v14.2.1 in the snow. Roads were not compacted like the other day, a little slippery, but overall doable at lower speeds. Enjoy the video and holiday music 🎶

Moving into the winter months, it will be very interesting to see how FSD handles even more concerning conditions, especially with black ice, freezing rain and snow mix, and other things that happen during colder conditions.
We are excited to test it ourselves, but I am waiting for heavy snowfall to make it to Pennsylvania so I can truly push it to the limit.

Tesla hosts Rome Mayor for first Italian FSD Supervised road demo
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets.
Tesla definitely seems to be actively engaging European officials on FSD’s capabilities, with the company hosting Rome Mayor Roberto Gualtieri and Mobility Assessor Eugenio Patanè for a hands-on road demonstration.
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets. This comes amid Tesla’s push for FSD’s EU regulatory approvals in the coming year.
Rome officials experience FSD Supervised
Tesla conducted the demo using a Model 3 equipped with Full Self-Driving (Supervised), tackling typical Roman traffic including complex intersections, roundabouts, pedestrian crossings and mixed users like cars, bikes and scooters.
The system showcased AI-based assisted driving, prioritizing safety while maintaining flow. FSD also handled overtakes and lane decisions, though with constant driver supervision.
Investor Andrea Stroppa detailed the event on X, noting the system’s potential to reduce severe collision risks by up to seven times compared to traditional driving, based on Tesla’s data from billions of global fleet miles. The session highlighted FSD’s role as an assistance tool in its Supervised form, not a replacement, with the driver fully responsible at all times.
Path to European rollout
Tesla has logged over 1 million kilometers of testing across 17 European countries, including Italy, to refine FSD for local conditions. The fact that Rome officials personally tested FSD Supervised bodes well for the program’s approval, as it suggests that key individuals are closely watching Tesla’s efforts and innovations.
Assessor Patanè also highlighted the administration’s interest in technologies that boost road safety and urban travel quality, viewing them as aids for both private and public transport while respecting rules.
Replies on X urged involving Italy’s Transport Ministry to speed approvals, with one user noting, “Great idea to involve the mayor! It would be necessary to involve components of the Ministry of Transport and the government as soon as possible: it’s they who can accelerate the approval of FSD in Italy.”
