SpaceX’s BFR and Raptor deemed “science-fiction” by French space agency manager
Speaking in a September 7th interview with French newspaper Courrier International, Dr. Francis Rocard – director of French space agency CNES’ solar system exploration program – had little good to say about SpaceX and CEO Elon Musk’s long-term ambitions in space, going so far as to question the CEO’s driving ethics and label the company’s next-generation rocket and propulsion system “science-fiction”.

Pehaps best known for its involvement in interplanetary space exploration missions like Rosetta and European launch provider Arianespace, CNES is providing a bit less than 25% of the $3.8 billion ESA is spending to develop the Ariane 6 rocket, as well as another $700m for the construction of a new launch pad and support facilities at the space agency’s French Guiana spaceport.
ArianeGroup, a public-private partnership and company, plans to begin replacing its highly successful Ariane 5 rocket with Ariane 6 as early as 2020 and is providing roughly $475 million of its own money to develop that launch vehicle. Ariane 5, which just completed its 100th successful launch on September 25th, costs between $165m and $220m (2016) per launch and is fully expendable, while Ariane 6 – also fully expendable – is targeting a slightly more practical cost between $100m and $130m per flight.
Differences between Ariane 5 and Ariane 6 are exceedingly minor, with the majority of differences found in the cost of each rocket. The end result for customers is essentially the exact same performance of Ariane 5 (or significantly worse) for at most a 40% discount. Ariane 6 will have light (2 solid rocket boosters) and heavy (4 SRBs) variants, and the light variant (known as Ariane 62) is expected to cost no more than 20% less than its heavy cousin while offering considerably less than half the performance.
This poses a major issue for ArianeGroup, as its current Ariane 5 only marginally functions as a commercial rocket thanks to an extensive reliance on dual-satellite launches, in which two different payloads are manifested on the same rocket in order to halve the cost each customer must pay. According to Arianespace, the best possible price a customer might wind up paying for one of Ariane 5’s two slots is ~$60m, essentially the same as the base price for a dedicated Falcon 9 launch. The problem, however, lies in the reality that Ariane 62 will be effectively incapable of performing the same dual-manifest launches but end up costing significantly more for a dedicated launch than the $60m-$100m Ariane 5 customers currently expect.

Ariane 64, at most a 40% cheaper replacement for Ariane 5, doesn’t even have a tentative launch debut date set, while Ariane 62 is pencilled in for a 2020 debut with several more launches soon after, potentially ramping up to a dozen missions per year in the mid-2020s. Rocard, while not directly involved in CNES’ own tenative work with reusable rocket experiments or its relationship with Ariane rockets, placed himself in an inopportune position by so bluntly dismissed and demeaning the near to long-term ambitions of SpaceX.
Not only are BFR and Raptor quite literally real enough to touch, but SpaceX’s Falcon 9 Block 5 is beginning to ramp up launch and reuse activities, placing the launch upstart in a position where the long-term survival – let alone success – of ArianeGroup and its Ariane 6 rockets seems no less likely than SpaceX’s realization of its Mars aspirations in the 2020s and 2030s. May the best rockets win.

Trump’s auto tariffs spark concerns in Japan

Japan expressed concern over President Trump’s auto tariffs, citing inconsistencies with a 2019 bilateral trade deal signed with the U.S.
Prime Minister Shigeru Ishiba said Japan is committed to the 2019 agreement despite current concerns over President Trump’s new tariffs.
Trump’s tariffs impose a 25% duty on imported vehicles, effective April 3, 2025, and auto parts duties will be imposed in May. The 2019 U.S.-Japan trade deal, signed during Trump’s first term, reduced tariffs on U.S. farm goods and Japanese machine tools.
Then-Prime Minister Shinzo Abe secured assurances from Trump, stating, “Between President Trump and I, this has been firmly confirmed that no further, additional tariffs will imposed.”
The 2019 bilateral trade deal did not cover auto trade between the United States and Japan. However, at the time, Prime Minister Abe had received assurances from President Trump that the U.S. would not impose national security tariffs on Japanese car imports. As such, the deal avoided higher U.S. car duties.
According to Reuters, Japan faces Trump’s 24% tariff on its exports to the United States, which were paused until July. Trump’s 25% auto tariff and a 10% universal rate remain intact, impacting Japan’s car-heavy economy.
Ishiba addressed the issue in parliament, noting, “Japan has grave concern over the consistency” between the tariffs and the 2019 bilateral deal. “We will continue to convey our stance (to the U.S.) from this standpoint,” he added, clarifying that Japan has no plans to terminate the agreement. The deal excluded automobile trade and remains a cornerstone of bilateral relations.
Japan’s trade negotiator, Ryosei Akazawa, visited Washington last week to discuss trade issues, including non-tariff barriers and exchange rates. Finance Minister Katsunobu Kato is set to meet U.S. Treasury Secretary Scott Bessent this week to address currency concerns, signaling Japan’s proactive diplomacy.
Japan’s firm stance reflects its intent to protect its auto sector while navigating U.S. trade policies. As talks continue, the outcome could shape bilateral trade dynamics and influence Japan’s export strategy amid ongoing tariff uncertainties.

Elon Musk dubs lawsuit alleging false Tesla odometer readings “idiotic”
The lawsuit alleged that Tesla’s odometer readings use “predictive algorithms” instead of actual mileage driven.

Elon Musk has responded sharply to a lawsuit alleging that Tesla speeds up its vehicles’ odometers to avoid paying for warranty-covered repairs.
Musk’s comment about the lawsuit’s allegations were posted on social media platform X.
The Lawsuit’s Allegations
The proposed class-action lawsuit claimed that Tesla is speeding up its vehicles’ odometers so that they can fall out of warranty quicker. This system, the lawsuit alleged, allows Tesla to save a significant amount of money in repairs.
The lawsuit’s plaintiff is Los Angeles resident Nyree Hinton, who alleged that his 2020 Tesla Model Y’s odometer readings reflect energy consumption, driver behavior and “predictive algorithms” instead of actual mileage driven, as noted in a Reuters report.
Hinton claimed that based on other vehicles and driving history, his car was stating that he was driving 72 miles a day when he usually drove just 20 miles at most. Because of this, Hinton alleged that his basic warranty expired well ahead of schedule, resulting in him paying $10,000 for a suspension repair that he believes should have been covered by warranty.
“By tying warranty limits and lease mileage caps to inflated ‘odometer’ readings, Tesla increases repair revenue, reduces warranty obligations, and compels consumers to purchase extended warranties prematurely,” the lawsuit noted.
Elon Musk’s Response
Tesla and its legal team have fully denied all material allegations that were outlined in the proposed class-action lawsuit. In a comment to longtime FSD user @WholeMarsBlog on X, Tesla CEO Elon Musk also criticized the proposed class-action lawsuit. “This is idiotic,” the CEO wrote in a post on X.
Veteran EV owners have also stated on social media that the lawsuit’s claims were inaccurate since Tesla’s odometers do not, in any way, use predictive algorithms. Others also pointed out that repairs are not a major source of profit for Teslas because the company’s vehicles tend to last long without requiring maintenance or spare parts.

Bizarre Tesla Cybertruck attacker in South Korea arrested and detained
The man is also accused of assaulting several people and damaging other vehicles during the incident.

A man who attacked a Tesla Cybertruck in South Korea’s Gangnam district has been arrested and detained.
As per reports, the man is also accused of assaulting a person and damaging several other vehicles during the incident.
The Incident
As per authorities, the suspect, who is in his 30s and is dubbed “Mr. A” (suspect names are typically not disclosed in South Korea to protect privacy and prevent possible prejudice), allegedly assaulted a hotel employee on the morning of April 15.
Following the assault on the hotel employee, the suspect reportedly knocked over a delivery motorcycle. He then went over and kicked a Tesla Cybertruck that was owned by a nearby medical facility. One of the all-electric truck’s side mirrors was damaged due to the attack.
As per a News 1 Korea report, Mr. A has also been accused of kicking four BMW vehicles at a nearby auto shop. The BMWs’ passenger side doors were damaged by the suspect.
Charges and Arrest
As per the Seoul Gangnam Police Station in an announcement, an investigation into the incident is underway. The suspect was arrested on charges of special assault, property damage, and obstruction of business.
Authorities apprehended Mr. A in Seongnam, Gyeonggi Province, on April 18. An arrest warrant from the court was released the day after.
Cybertruck Attacks
The Tesla Cybertruck attack in South Korea is quite bizarre as the suspect assaulted both people and vehicles. The incident, if any, seems to be quite different from the attacks on Teslas that have been reported in the United States and Europe, which seemed to be political in nature and a response to CEO Elon Musk’s close relationship with President Donald Trump.
