SpaceX tests Starship and Frankenstein ‘test tank’ simultaneously
After another few weeks of downtime, SpaceX has simultaneously tested the first orbital-class Starship prototype and a Frankenstein-esque ‘test tank’ at its South Texas facilities. While nothing that occurred was all that visually spectacular, the afternoon of testing was still noteworthy for a couple of reasons.
First up, following a successful six-engine Raptor static fire – the first in Starbase history – on November 12th, all signs pointed to Starship S20 attempting another static fire (its fourth) on December 1st. In the almost three weeks of inactivity between those planned tests, SpaceX likely performed extensive inspections of the pathfinder prototype and its Raptor engines. Technicians also repaired the minor heat shield damage and tile loss that testing incurred and patched a few other ‘holes’, effectively leaving Ship 20 with the first fully finished heat shield by the end of November.
Earlier this week, one of the few remaining Boca Chica Village residents received a safety notice from SpaceX indicating that a static fire test was scheduled on Wednesday, December 1st – followed soon after by a notice to mariners (NOTAM) warning boaters to keep to a safe distance. Two hours into the 10am to 6pm CST test window, Starship S20 was already venting and starting to get frosty, confirming that propellant loading had begun. A little over an hour later, it was clear that SpaceX had aborted the first static fire attempt of the day. For the next three hours, Ship 20 exhibited some unusual behavior including new vents, an apparent header tank pressurization or fill test, and still more odd venting in new places.
In the middle of Starship’s weird nose-related testing, SpaceX began simultaneously loading a new ‘test tank’ known as B2.1 with liquid nitrogen (LN2) – marking the first truly simultaneous test of multiple Starship test articles. As Ship 20 seemingly detanked for the second time that day, the B2.1 tank was fully loaded with LN2 and apparently pressure-tested not long after. A few hours later, the test tank was also detanked and the road to the pad was reopened, marking the end of the day’s testing.
Normally, nothing is particularly unusual or noteworthy about test tank testing. Since January 2020, SpaceX has routinely built and tested tanks that are effectively just shorter versions of actual tanks and hardware, using them to qualify changes to Starship’s design, materials, operations, and more before applying those changes to full-size prototypes. B2.1 is the tenth dedicated test tank to reach the launch pad in a little under two years.
Normally, the ‘B2.1’ name SpaceX has given the tank would imply that it’s a newer booster test tank (using Bx instead of BNx) following in the footsteps of BN2.1, which passed cryogenic and load testing this summer. Instead, though, B2.1 is a bit of a nightmarish amalgamation of seemingly random Starship and Super Heavy parts. Its forward dome is an old, unused booster section complete with the hexagonal structure grid fins would have been brace against. Its aft section is a booster thrust structure. Up to that point, it’s effectively just a copy of BN2.1.
However, SpaceX inexplicably installed a Starship thrust dome inside B2.1’s booster thrust structure, creating a test tank with no obvious relevance to any conceivable Starship or Super Heavy design or prototype. Further, SpaceX rolled B2.1 to the launch site for testing only after installing it on an unused device that’s believed to be the aft half of a dedicated booster structural test stand. In theory, a sort of ‘cap’ would be fitted on top of a booster or test tank installed in the stand’s base and strong cables would connect the two, allowing SpaceX to subject prototypes to compressive stress – like, perhaps, the forces a booster might experience while carrying a fully-fueled 1300-ton Starship to space. The upper half of that test structure has yet to be moved to the launch site.
Altogether, the weird half-complete test stand and bizarre fusion of ship and booster parts make B2.1’s purpose and initial testing a complete mystery. It’s unclear what value it provides that makes it more of a priority than, say, finally starting to test the first flightworthy Super Heavy booster (B4). Ultimately, the most interesting thing about B2.1’s test debut is the fact that it appears to mark the first use of Starbase’s brand new orbital tank farm, which is approaching completion.

China considering EV acceleration limits to curb high-speed accidents
If approved, the regulation would be a national standard.
Recent reports have emerged stating that China is considering new national standards that would restrict how fast electric vehicles can accelerate upon each startup. The potential regulation is reportedly being considered amidst a rise in EV-related crashes.
The draft for the proposed regulation was released by the Ministry of Public Security on November 10. If approved, the regulation would be a national standard.
New regulation targets default performance limits
Under the proposal, all passenger vehicles would start in a state where acceleration from 0–100 km/h (0-60 mph) would take no less than five seconds. This rule would apply to both pure EVs and plug-in hybrids, and it is aimed at preventing unintended acceleration caused by driver inexperience or surprise torque delivery.
The public has until January 10, 2026, to submit feedback before the rule is finalized, as noted in a CNEV Post report.
Authorities have stated that the change reflects growing safety concerns amidst the arrival of more powerful electric cars. The new regulation would make it mandatory for drivers to deliberately engage performance modes, ensuring they are aware and ready for their vehicles’ increased power output before accelerating.
A rise in accidents
China’s EV sector has seen an explosion of high-powered models, some capable of 0–100 km/h acceleration in under two seconds. These speeds were once reserved for supercars, but some electric cars such as the Xiaomi SU7 Ultra offer such performance at an affordable cost.
However, authorities have observed that this performance has led to an uptick in accidents. I recent years, incidents of crashes involving lack of control in vehicles with rapid acceleration have risen, as per an explanatory note accompanying the draft.
Part of this is due to drivers seemingly being unprepared for the power of their own vehicles. For context, driving schools in China typically use cars that accelerate to 100 km/h in more than 5 seconds. This level of acceleration is also typical in combustion-powered cars.

Tesla Superchargers crowned best EV charging network in the UK for 2025
The Tesla Supercharger network was voted Best Large EV Charging Network for the second consecutive year.
Tesla has once again claimed the top spot in the UK’s most anticipated EV charging satisfaction survey. As per Zapmap’s 2025 driver satisfaction rankings, the Tesla Supercharger network was voted Best Large EV Charging Network for the second consecutive year.
The annual survey, based on thousands of EV driver responses, measures reliability, ease of use, and payment experience across the UK’s public charging landscape.
Tesla tops the survey’s “Large” category
Zapmap’s 2025 rankings, which were drawn from nearly 4,000 battery electric vehicle (BEV) drivers, reflect how quickly public charging is evolving across the UK. For the survey’s “Large” network class, which includes systems with over 500 devices, Tesla once again stood out for reliability and cost efficiency.
The automaker now offers 1,115 open Supercharger devices at 97 public sites, roughly 54% of its total UK network. That’s a 40% increase in public availability compared to September 2024. A particularly appreciated aspect of the Supercharger network is its cost, which continues to be “significantly lower prices than most rapid/ultra-rapid networks, with drivers also appreciating its reliability,” Zapmap noted.
Tesla Regional Manager’s comments
Ollie Dodd, Senior Regional Manager for Northern Europe Charging at Tesla, shared his appreciation for the Supercharger network’s award.
“We’re thrilled to win Zapmap’s Best EV Charging Network for the second year in a row. Being recognized by the drivers themselves shows that our customer-centric and data-driven approach to building sites is well-received. We look forward to showcasing more customer-centric features in 2026 as we expand the network further and look towards new initiatives in roaming and payment methods,” he said.
Conducted during September and October 2025, Zapmap’s eighth annual survey found that reliability and payment flexibility remain top priorities among EV drivers, two things that the Supercharger network particularly excels in. Fortunately for UK EV owners, the Supercharger network is also aggressively growing.
