SpaceX ramps up Falcon 9, Falcon Heavy booster testing in Central Texas
In the latest twist in the saga of SpaceX’s McGregor, Texas testing facilities, a new Falcon 9 booster has managed to sneak past a network of unofficial observers to create a whole different kind of rocket traffic jam.
On the heels of a single day (March 19th) filled with at least five different tests of Merlin and Raptor engines and a Falcon Heavy booster, SpaceX was apparently satisfied with the results from the Heavy center core’s final major qualification test. On March 24th, the day after yet another five-test day in McGregor, SpaceX hooked up a crane to B1066 and brought the booster horizontal to prepare for transport to Cape Canaveral, Florida.
That very same day, a local resident and avid McGregor hawk spotted a new Falcon 9 booster arriving (or recently uncovered) at the test facility. Less than 24 hours later, the Falcon 9 booster was brought vertical and installed on the facility’s largest test stand for a routine qualification static fire. For McGregor, particularly after a relatively slow 12-18 months of Falcon first stage testing, having two new boosters simultaneously onsite – let alone two new boosters vertical just ~24 hours apart – is a massive change of pace.
In January 2021, some two months after arriving in Texas, the second of at least two new Falcon Heavy side boosters (B1064 and B1065) went vertical at McGregor, quickly wrapped up its static fire test campaign, and arrived at Cape Canaveral by the end of the month. Roughly a week later, Falcon Heavy Flight 4’s center core (B1066) arrived in McGregor and went vertical a few weeks after that. It’s possible that B1066 performed a static fire test that month, but the booster did unequivocally fire up on March 19th.
Days later, Falcon 9 B1067 is vertical on the same McGregor booster test stand and could potentially fire up anywhere from a few days to a few weeks from now. Combined with an October 2020 static fire of the first Falcon Heavy Flight 4 side booster static fire, all three of the massive rocket’s first stage boosters will likely be qualified and ready for flight within a week or two.
Notably, for McGregor, three new Falcon booster static fire tests in approximately three (or even four) months is a huge change of pace. Thanks almost exclusively to the success of Falcon Block 5 reusability since its 2018 debut, SpaceX booster production has consistently declined year over year, dropping to just five new booster deliveries in 2020 – the lowest production rate since 2013.
SpaceX has been ramping up Falcon fairing and expendable upper stage production to levels never seen before to achieve a record 26 launches in 2020, potentially explaining that record low. However, in 2021, McGregor appears to be on track to test and ship three new boosters in four months (or less), extrapolating to an annual cadence of nine or more booster tests.
Aside from last week’s F9 B1067 surprise, SpaceX needs to build, test, and deliver at least one more Falcon Heavy center core between now and the end of Q3 for an October launch. If SpaceX can partially maintain the throughput implied by delivering B1066 and B1067 to McGregor just seven weeks apart, it’s not infeasible that the company could manage the first uptick in Falcon booster production since 2017.
Tesla is beginning to roll out Full Self-Driving Supervised v14.3.9 with a new active safety layer that can take control even when the driver is operating the car manually.
Tesla AI said the software can activate FSD on the driver’s behalf when an imminent collision is detected and Automatic Emergency Braking may not be enough. It may also engage if the system detects heavy distraction or an accidental FSD disengagement.
FSD Supervised v14.3.9 starting to roll out shortly
This release includes a new active safety feature set: FSD Supervised can now activate on your behalf when an imminent collision is detected and Automatic Emergency Braking (AEB) may not be enough.
It may also engage if we…

The capability is essentially Automatic Collision Evasion. However, unlike conventional AEB, which mainly applies the brakes in a straight line, this feature can use steering, braking, and acceleration together if the car calculates that stopping alone will not prevent impact and a safer path exists. The system may change lanes or move toward a shoulder when conditions allow, then continue driving after the immediate threat is handled rather than simply coming to a stop.
The intervention is meant as a last-resort safety net, not a replacement for attentive driving.
Tesla Full Self-Driving v14.3.7 early review: FSD saved me from an accident
Tesla’s own description still frames FSD as supervised assistance. Secondary reports on internal release notes say the feature can fire while the car is being driven manually if cabin-camera monitoring suggests the driver is not sufficiently attentive, such as reaching toward the back seat, or if FSD appears to have been turned off unintentionally.
After the emergency maneuver, the car is expected to alert the driver and request a return to manual control.
The safety case is straightforward. Many collisions happen in the last second because a driver is looking away, fumbles a control, or faces an obstacle that braking cannot fully solve. A system that can both recognize that AEB is insufficient and execute a coordinated evasive path can reduce those remaining high-severity events.
Re-engaging after accidental disengagement also addresses a practical failure mode: a small steering nudge that drops FSD at the worst moment. The advantage is a background safety net that uses the same vision stack already running in v14, instead of leaving the car solely to emergency braking once the driver is no longer in command.
The feature still depends on FSD being enabled and, according to reports, an active FSD purchase or subscription. It does not make the vehicle unsupervised. Drivers remain responsible, and Tesla has not published how often the system is expected to intervene or how it will handle false positives.
If the rollout is conservative and the false-alarm rate stays low, the update is a meaningful step: FSD is no longer only a feature the driver turns on. In the rare moments when disaster is already forming, it can step in.
Tesla launched the all-electric, steering wheel-less, and pedal-less Cybercab last night at a quiet and small event in downtown Austin, Texas.
The launch, which marked the beginning of unsupervised ride-hailing for Tesla’s Robotaxi platform with Cybercab, has already caught the attention of the National Highway Traffic Safety Administration (NHTSA) who has more questions.
NHTSA opened an Audit Query (AQ) into the Cybercab’s Federal Motor Vehicle Safety Standards (FMVSS) certification that Tesla gave the vehicle. Manufacturers self-certify vehicles much of the time to avoid excessive regulatory delays.

However, the agency needs more information; it said in a summary:
“On September 3, 2026, Tesla began commercial deployment with a small number of its Cybercab vehicles in Austin, Texas. Tesla notified the Agency that it certified those Cybercab vehicles as compliant with all applicable Federal Motor Vehicle Safety Standards (FMVSS). Tesla also notified the Agency that it plans to gradually expand commercial deployment of the Cybercab to include additional vehicles and locations.”
It also went on to state that the Cybercab lacks traditional automotive controls, which is a groundbreaking move. The process is entirely new to the NHTSA, which gives the agency some leverage to put Tesla’s launch under a microscope:
“The vehicles lack permanently attached, conventional manual controls, such as a brake pedal, gas pedal, steering wheel, and mirrors. NHTSA is opening this AQ to examine the process and technical data on which Tesla relied when certifying the Cybercab and related issues. Among other things, NHTSA will consider the extent to which Tesla’s certification depended on determinations that certain FMVSS are inapplicable to the Cybercab.”
Tesla has added 45 Cybercab units to its fleet of Robotaxi-enabled cars in Austin, according to public documents the company submitted to the State of Texas over the past week. Enabling this level of self-driving is something Tesla has worked toward for many years, and now that it is finally here, it seems more than reasonable that regulatory agencies will have some questions.
Many outlets might try to frame this as a negative, but it is truly an agency looking to gain more information about groundbreaking tech that Tesla has been developing for years.
In an effort to keep riders, pedestrians, and property safe, any and all data accumulated from these first days, weeks, and months of rides will likely be shared with the NHTSA to enable broader rollout strategies across the United States and more in the future.

Tesla Cybercab is coming to Asia this month as US service officially begins
Tesla Asia says Cybercab will be on display in Hong Kong, Tokyo, Beijing and Shanghai this month.
Tesla’s Cybercab is heading to Asia. The official Tesla Asia account posted on X Thursday, inviting Cybercab fans to “Come experience the future of autonomy in Hong Kong, Tokyo, Beijing & Shanghai.” The post went up within hours of Tesla’s own Cybercab milestone in Texas, where the company said Thursday it had begun offering rides in across Austin.
Exact dates and venues for the Asia tour haven’t been released yet, though Tesla Hong Kong replied to the announcement with “Cybercab will be on display in Hong Kong soon,” while Tesla Japan’s response pointed fans to a sign up page for updates. Neither post mentions test rides or a service area, and nothing so far suggests Tesla is launching Robotaxi operations in any of the four cities. Based on how Tesla has run past Cybercab tours, in Europe in late 2024 and at US shopping centers that same December, the Asia stops are almost certainly static displays at Tesla stores or public venues as a means to stimulate buzz for its future driverless ride-hailing service in the big cities.

The timing lines up with Tesla’s only prior Cybercab appearance in the region, a booth at the China International Import Expo in Shanghai last November, which Teslarati covered at the time. At that event, Tesla’s regional general manager for Shanghai framed the car as evidence of the company’s broader mission, a message Tesla has since formalized in its Master Plan Part IV, which states that “autonomous vehicles have the capacity to dramatically improve the affordability, availability and safety of transportation while reducing pollution, particularly in our increasingly dense global cities.” The same document is where Tesla lays out its “sustainable abundance” framing for Cybercab and Optimus alike, describing the two as the hardware behind an AI driven push to cut the cost of transportation and labor at scale.
Whether Cybercab actually operates as a robotaxi anywhere in Asia remains an open question, considering China has already pushed an autonomous ride-hailing market that’s run on homegrown players like Baidu’s Apollo Go and Pony AI. For now, the four city tour reads as a marketing push timed to Austin’s momentum.
