On Saturday evening, SpaceX CEO Elon Musk landed in Waco, Texas – perhaps along with additional SpaceX propulsion engineers – for the critical static fire debut of the first “radically redesigned” Raptor engine, built to power BFR’s Starship upper stage and Super Heavy booster.

If the first operationalized Raptor’s static fire tests go well, there are several possible routes the test program could take, all of which will end up with this engine and several others being tested and ultimately installed on the Starship hopper (Starhopper) prototype under construction roughly 500 miles (800 km) south of SpaceX’s Raptor test cell.

Shortly after Musk revealed official photos of the first operationalized Raptor preparing for an inaugural static fire test at SpaceX’s McGregor, Texas facilities, the SpaceX and Tesla CEO’s private jet was seen landing at Waco, Texas around sunset. Although all SpaceX technical expertise needed for Raptor’s first ignition was probably already on site several days prior, Musk has been known to offer seats on his private planes to SpaceX and Tesla employees when a critical group is needed away from their normal base of operations. The best examples come from Tesla engineering expertise sometimes traveling between Fremont and Gigafactory 1 when needed, often to solve production holdups.

Regardless of whether he was traveling with members of the SpaceX propulsion team, Musk’s arrival at McGregor yesterday signified that Raptor Block 1’s first integrated hot-fire was imminent. Assuming no attempt was made on Saturday night or Sunday morning, SpaceX technicians and engineers are presumably still working on installing what is effectively a new rocket engine and ensuring that Raptor’s test cells – extensively overhauled and upgraded for the occasion – are working as intended. While the development Raptors SpaceX built hovered around 1000 kN (~100t) of thrust, also roughly the same as Merlin 1D, the Raptor now on stand in Texas is reportedly a 200 ton-class engine or more than double the thrust of any single engine SpaceX engineers and technicians have built or test-fired in 15 years of engine development.

A fork in the R&D road

Prior to completing Raptor Block 1 (unofficial designation), SpaceX cumulatively test-fired dev Raptors for far more than 1200 seconds over the course of more than 24 months. It’s unclear how extensively the company’s engineers will be able to test the pathfinder hardware built on the back of that extensive test program. Nominally, one would expect hundreds or thousands of seconds of additional testing to properly characterize the design and production of a brand-new, optimized engine like Raptor while primarily ensuring that it performs within engineering specifications.

Knowing CEO Elon Musk’s self-admitted tendency to push for impractical deadlines and schedules that often appeared rushed for the sake of rushing, it’s not impossible that the first Raptors could find themselves installed on the Boca Chica-based Starhopper test article after Merlin-esque acceptance testing and nothing more. For M1D and MVac, acceptance testing usually takes the shape of a full-duration burn with throttle and gimbal activity to closely simulate a true Falcon 9 or Heavy launch. For the 200-ton Raptor now in Texas, comparable acceptance testing could take a variety of forms, ranging from short Starhopper-relevant burns (10-60 seconds for small hops) to simulating conditions during a Super Heavy launch and landing or even a 6 or 7-minute orbital insertion burn indicative of the performance needed for Starship.

A trio of roughshod Raptor mockups were installed on Starhopper around Jan. 1, presumably helping engineers and technicians prepare to install the real thing. (NASASpaceflight – bocachicagal.

Depending on the interplay between the route SpaceX engineers would likely prefer and the Starhopper test schedule executives and managers might want, this first Raptor engine (and two more soon to follow) could be installed on Starhopper anywhere from a few weeks to several months from now. Elon Musk indicated in early January that he expected hop tests would occur 4-8 weeks later, shortly followed by unplanned damage to the craft’s nose cone that pushed the debut back “a few weeks”.

Realistically, hop tests should thus be expected to begin no earlier than (NET) 8-12 weeks from the first week of January, translating to NET March or April. This would give SpaceX propulsion engineers a decent amount of time to gain at least a few hundred (or maybe 1000+) seconds of experience operating the newest and most advanced iteration of Raptor.

Tesla Robotaxi vs. New York Taxi: Why the Yellow Cab has a lot to lose

Tesla Robotaxi could spell the beginning of the end of the New York City yellow cab.

Published

on

Tesla appears to be on its way into the Big Apple, and a traditional Yellow Cab in New York City might be a thing of the past in the near future.

As Tesla continues to put an immense focus on the rollout of its Robotaxi platform, it is evident that driverless ride-hailing modes of transportation could truly be the way that many choose to get around. This is especially prevalent in cities like New York, where many people do not own cars. Instead, they choose to walk to hail a cab.

Tesla Robotaxi is headed to New York City, but one thing is in its way

But the limited number of medallions available for taxi drivers in New York City, as well as several other points of emphasis, seem to show the future is here and yellow cabs might soon be a thing of the past.

Instead of working tirelessly to pay off the debt from medallions, entrepreneurs could soon just buy a Tesla and have it work autonomously in New York City. Tesla executives have mentioned figures as high as $50,000 per year in terms of passive income from Robotaxi operation.

That is just the tip of the iceberg, and Robotaxi presents not only one but at least five distinct advantages over the traditional cab platform. With Tesla starting to seek employees to operate Robotaxi rides in New York, according to recent job postings, New York City cabs should prepare for the disruption Tesla could potentially cause.

Lower Operational Costs and Cheaper Fares

Uber and Lyft have already undercut the costs of New York City taxis, but Robotaxi is starting to undercut even those ride-sharing programs in Austin, Texas.

In terms of how much cheaper Robotaxi will be than cabs, it is an exponential measurement over time. Robotaxi will not require salaries, benefits, or tips, and the cost of Robotaxi could end up being just a fraction of what the same ride would cost in a cab.

This feeds right back into medallion expenses and union wages: even buying a Tesla in the next few years that has the capability to operate as a Robotaxi will be a fraction of what medallions cost, which is sometimes $200,000.

Availability and Scalability

Cabs are available at all hours of the day, but at certain times, they are less available.

Robotaxis can technically operate without breaks, other than charging. Tesla has an immense focus on scaling its Robotaxi platform anyway, and once it is available for the public to use in their personal cars, Model Ys and Cybercabs could be roaming the streets of the five boroughs with more reliability and lower wait times than traditional cabs could ever offer.

This is an issue that is even more relevant in smaller cities or less congested portions of New York.

Safer and More Efficient Rides

Tesla’s Full Self-Driving technology has reported recent safety figures that are ten times less likely to be involved in an accident than a human. Tesla releases a Safety Report for each quarter that proves its safety against human drivers.

As Full Self-Driving continues to advance, it will get better. Riders who want a stable and safe ride could seek Robotaxi instead of going with a human driver. This is something that we’ll likely see more of in the future as sentiment on autonomous driving grows.

Trust in autonomous vehicles has increased substantially over the past ten years. In 2015, surveys showed that trust in autonomous vehicles was low, with only 23 percent of Americans showing that they’d ride in a driverless car.

In 2021, another study performed that asked the same question showed 57 percent of adults would try an autonomous car for their travel.

Seamless App Integration and User Experience

Taxis are not always the most entertaining to ride in, and sometimes they are even more difficult to get a ride in. Robotaxi has already shown to be an incredibly user-friendly experience, with riders being able to choose what temperature the cabin is and what music they want to listen to in the cabin.

The addition of a rear screen also allows riders to choose from a selection of games or YouTube videos in the car.

Hailing a vehicle was basically resolved with the use of Uber and Lyft. Robotaxi is just as good, if not better, from an app standpoint, especially as the in-car climate is able to be adjusted from the Robotaxi app.

Music from one Robotaxi will continue to play in your next one, too. It’s a small luxury, but it’s a feature that is an improvement over a traditional taxi.

The Push for Sustainability by New York City

New York is pushing for a city-owned fleet of all-electric vehicles by 2027.

Its green initiatives, including the Green Rides Initiative, have pushed the city’s rideshare trips to be conducted by either zero-emission or wheelchair accessible vehicles by 2030.

The focus by consumers to use green or zero-emission vehicles could also steer right into the direction of Tesla Robotaxi, as none of the vehicles in the Robotaxi fleet will be anything but all-electric Teslas.

Carbon neutrality is a goal of the City and its residents. Moving forward, we could see these programs start to put immense pressure on the yellow cab, which could eventually be a thing of the past.

Tesla plans to use Unreal Engine for driver visualization with crazy upgrade

This could change the way Driver Visualization looks for Tesla owners.

Tesla looks to be planning a major upgrade to its driver visualization for Autopilot with a crazy upgrade from its current version.

Tesla’s driver visualization appears on the center screen and shows the vehicle, its surroundings, and, when it is operating on Autopilot or Full Self-Driving, shows the route of travel.

It has improved over the years, and even includes things like pedestrians, pets, and the shapes of other vehicles. It also helps with manual driving because it can be a good representation of your surroundings when trying to change lanes or merge in traffic.

However, it appears Tesla is planning a pretty substantial upgrade with the

Coding found in the 2025.20 firmware by Tesla hacker greentheonly showed the company is planning to utilize Unreal Engine for Autopilot visualization. He said the one Tesla currently uses is “godot-based.”

Unreal Engine is a 3D computer graphics game engine that was developed by Epic Games, the developer of the popular third-party shooter game Fortnite. It was first released back in 1998, and the most recent version is Unreal Engine 5. The sixth version is in development, and it could be out in 2027 or 2028.

However, Tesla could use it for a more realistic representation of vehicle surroundings. It would undoubtedly improve driver visualization, creating a smoother and freer-flowing depiction of what is outside of the car.

SpaceX is rolling out a new feature to Starlink that could be a lifesaver in some instances, but more of a luxury for others.

Starlink is the satellite internet service that Elon Musk’s company SpaceX launched several years ago. It has been adopted by many people at their homes, many airlines on their planes, and many maritime companies on their ships.

It has been a great way for customers to relieve themselves of the contracts and hidden fees of traditional internet service providers.

Now, Starlink is rolling out a new service feature on its units called “Standby Mode,” which is part of Pause Mode. The company notified customers of the change in an email:

“We’re reaching out to you to let you know the Pause feature on your plan has been updated. Pause now includes Standby Mode, which comes with unlimited low-speed data for $5.00 per month, perfect for backup connectivity and emergency use. These updates will take effect in 30 days. All of your other plan features remain the same. You are able to cancel your service at any time for no charge.”

SpaceX did not define how fast these “low speeds” will be. However, there are people who have tested the Standby Mode, and they reported speeds of about 500 kilobytes per second.

The mode is ideal for people who might deal with internet or power outages, but still need to have some sort of internet access.

It could also be used as a backup for people who want to stay with their ISP, but would like to have some sort of alternative in case of an outage for any reason.
