General Motors’ (GM’s) driverless ride-hailing company Cruise has been hit with its latest fine, after the company failed to disclose certain details about an accident involving a pedestrian last October.

Cruise has agreed to pay a $500,000 criminal fine over the record it submitted following an accident with a pedestrian last October, as detailed by the Department of Justice (DOJ) in deferred prosecution that was revealed on November 14 (via Automotive News). The decision was made within the U.S. Attorney’s Office in the Northern District of California, and it comes as the most recent legal penalty the company has had to pay after regulators said it “omitted” and “misrepresented” details about the accident.

According to NHTSA special agent Cory Legars, who is overseeing the Cruise case, the fine is intended to help hold Cruise and its staff accountable, following a “lack of candor” in response to the 2023 crash in which a robotaxi dragged and pinned a pedestrian.

The DOJ echoed the company’s withholding of certain details following the accident, which caused “multiple traumatic injuries” for the pedestrian, according to emergency responders. Cruise has also been criticized over its response to the accident by other agencies, including the California Public Utilities Commission (CPUC) and the state’s Department of Motor Vehicles (DMV).

Along with the fine, Cruise must also implement a safety compliance program, submit yearly reports to the U.S. Attorney’s Office, and cooperate with all government agency investigations.

In a written statement, Cruise Chief Administrative Officer Craig Glidden said that company maintained a “firm commitment to transparency with our regulators.”

Cruise leadership pledges more transparency, greater culture of safety in new letter

Cruise’s October 2023 accident and other crash response fines

In the accident, which took place on October 2, 2023, a Cruise robotaxi struck a pedestrian moments after she had been hit by a car with a human driver. The pedestrian ended up in the path of the Cruise vehicle, which hit her, dragged her about 20 feet, and engaged an emergency stop sequence that caused the vehicle to stop on top of her with hazard lights on until authorities arrived.

Following the accident, the DMV and other agencies noted that Cruise avoided sharing certain details, including exactly what the robotaxi did after it ran over the individual. Weeks later, Cruise disclosed a more full version of events, but it was only after the DMV specifically requested more details. The agency also suspended Cruise’s permit to operate self-driving vehicles, effective immediately.

“Cruise’s omission hinders the ability of the department to effectively and timely evaluate the safe operation of Cruise vehicles and puts the safety of the public at risk,” said Bernard Soriano, DMV deputy director, after the accident.

In the following weeks and months, Cruise would go on to see a significant staff and executive shake-up, with its two co-founders resigning alongside several other high-level employees. The company also went on to let go of around a quarter of its staff, before hiring several new executives in attempts to regain public and regulator trust and relaunch the service.

Cruise is currently aiming to reboot driverless ride-hailing sometime this year, though it has faced multiple fines from agencies and regulators in addition to the $500,000 agreement with the DOJ.

In June, following months of commission deliberation, Cruise was ordered by the CPUC to pay the maximum penalty of $112,500 for its crash response, after the company originally lobbied for a fine of just $75,000. In September, the NHTSA ordered Cruise to pay a $1.5 million fee, along with submitting a corrective action plan and additional details on how the company plans to fulfill reporting standards in any future incidents.

Tesla patent aims to improve common on-road complaint

Published

Tesla is continuing to push the boundaries of vehicle dynamics, as its latest published patent, US12654505B2, or “Suspension Actuator System for a Vehicle,’ which has finally been pushed through.

The design, which is credited to inventors Brian Lee Doorlag, Avraham Kagan, and Justin Sill, introduces a sophisticated hybrid suspension design that blends active motor-driven control with strategic passive elements to deliver superior ride quality, energy efficiency, and resilience against road imperfections, especially potholes.

At the heart of the system is an active control element powered by an electric motor. This motor drives a belt connected to a ball nut assembly and threaded screw, which adjusts the effective length of the suspension strut in real time.

By extending or retracting, the actuator can lift or lower the wheel more accurately, which can end up countering road disturbances. Sensors, including accelerometers and wheel position monitors, feed data to a suspension control system that processes inputs and commands the motor instantly.

This active component doesn’t work alone. A low-rate air spring mounts in parallel with the actuator. Its primary role is to offset much of the vehicle’s static weight, dramatically reducing the power demand on the motor.

Without this, the active system would constantly fight gravity, draining energy and generating heat. The air spring handles steady-state loads efficiently, allowing the motor to focus on dynamic adjustments.

Complementing this is a series of passive control elementsa spring and an adaptive damper—placed between the actuator and the wheel. This setup filters high-frequency vibrations before they reach the active motor, preventing it from overworking on minor inputs. The adaptive damper, potentially magnetorheological or valve-controlled, further tunes damping electronically for optimal comfort and stability.

How It Differs from Traditional Suspensions

Traditional passive suspensions compromise between comfort and handling, while pure active systems can be power-hungry and complex. Tesla’s hybrid approach resolves this by delegating tasks: the parallel air spring manages weight and low-frequency body motions, the series elements absorb rapid vibrations, and the active actuator tackles larger, lower-frequency events.

The result is a smoother, more isolated cabin experience. High-frequency road noise and harshness diminish, while the vehicle maintains precise control during cornering or acceleration. Energy efficiency improves, too—lower motor loads mean reduced battery drain, potentially extending range in electric vehicles.

How It Mitigates Potholes Specifically

Potholes are a major challenge because they provide a sudden drop to the wheel plunge, jarring the body of the vehicle, risking damage. The patent explicitly addresses this. Upon detecting a pothole (via sensors or predictive mapping), the control system activates

the motor to retract the strut, effectively pulling the wheel upward to minimize downward excursion. The series spring/damper cushions the impact, while the parallel air spring maintains overall support.

This proactive “wheel retraction” prevents sharp jolts, preserving passenger comfort and protecting components. Integrated with Tesla’s road roughness mapping patents, the system could anticipate potholes from fleet data, enabling preemptive adjustments for even smoother navigation.

Future Implications for Tesla Vehicles

This technology builds on Tesla’s existing adaptive dampers and air suspension that is seen in Cybertruck, but advances toward fully active control. It could roll out to future models, including refreshed Cybertrucks or next-gen vehicles, enhancing both daily drivability and off-road capability. By minimizing power use and complexity, it aligns with Tesla’s goals of efficiency and scalability.

In summary, US12654505B2 exemplifies Tesla’s engineering philosophy: intelligent integration over brute force. This hybrid suspension promises quieter, more comfortable rides and robust pothole defense, potentially setting a new standard for automotive comfort. As Tesla iterates, drivers can look forward to roads feeling far less rough.

The Tesla Cybercab got a huge nod of support from a Texas Department of Transportation official, who said the all-electric ride-hailing vehicle is “a tangible example of how quickly our transportation system is evolving.”

The Cybercab was present at the Texas Department of Transportation’s Texas Innovation Invitational, an event held each year that allows innovative companies to showcase advancements in transportation.

Tesla Cybercab specs revealed: range, curb weight, range ratings, and more

Marc Williams, the Texas Department of Transportation’s Executive Director, sat in a Cybercab and shared his thoughts in an extensive post on LinkedIn.

Williams’s comments show how Tesla, with its Cybercab, is leading the charge of passenger travel and how it’s changing so rapidly. He notes the absence of traditional driving controls as a telltale sign that the Cybercab is a catalyst for major automotive change, taking controls from drivers and turning them into full-time passengers.

“Observing this vehicle firsthand–from its design and butterfly doors to the cargo trunk configuration–provides a tangible example of how quickly our transportation system is evolving. Sitting inside the cabin, the complete absence of traditional driver controls underscores a significant shift in mobility and vehicle design. No steering wheel, no accelerator, no brake. Only a single touchscreen monitor.”

Tesla has had a great relationship with the State of Texas, especially with its Robotaxi ambitions. Currently, Texas has Tesla Robotaxi operating in multiple cities: Dallas, Austin, San Antonio, and Houston. The company’s main manufacturing plant is also located just outside Austin, and Tesla moved its headquarters to the state several years ago.

The Cybercab is a purpose-built, fully autonomous, two-passenger Robotaxi vehicle designed specifically for ride-hailing services. Tesla has said for years it would be built without a steering wheel or pedals present, although there is still quite a bit of debate among the community regarding that potential.

Earlier this week, we received official word that the EPA had provided the Cybercab with a Certificate of Conformity, giving Tesla permission to enter the vehicle into the chain of public commerce. It is officially ready for roads.

The big question for Tesla remains: Can it solve self-driving before the steering-wheel-less Cybercab officially enters production?

The Boring Company just doubled its tunneling power in Nashville

The Boring Company’s Prufrock MB2 is commissioned and ready to mine beneath Nashville’s streets.

The Boring Company’s second tunnel boring machine, Prufrock MB2, is officially ready to dig in Nashville. The company confirmed the news on X, posting: “Prufrock-MB2 is ready to mine in Nashville! MB2 commissioning is complete, including the brief 11 rpm rotation shown here. Will MB2 catch up to MB1, who had quite the head start? And Prufrock-MB3 ships in August!”

MB2 arrives with meaningful improvements over its predecessor. Lessons learned from the launch and operation of MB1 have already been applied to MB2 to improve efficiency and prepare the machine for launch.

Traditional tunnel boring machines operate in a stop-and-go cycle, digging roughly five feet, halt, erect precast concrete segments to line the tunnel wall, then resume. That repeated interruption is one of the main reasons conventional tunneling is slow and expensive. Prufrock is designed to install the tunnel liner simultaneously with mining, eliminating the need to stop every five feet. The machine also skips the need for excavated launch pits. Prufrock arrives on a truck, tilts down, and launches into the ground within 24 hours. And when the tunnel is complete, it emerges from the ground and drives to its next launch site on a trailer, eliminating the need for expensive cranes or pit excavation. The machine is also fully electric and runs with zero people in the tunnel during normal operations, controlled remotely from a surface operations center.

It won’t be long before we hear of another major update on The Boring Company’s Music City Loop project – a planned underground transit network beneath Nashville that would move passengers in electric vehicles through a series of tunnels at highway speeds, and bypassing surface traffic entirely. Nashville was selected in part because of its strong rock conditions that suits the Prufrock machines well, and relatively less regulatory hurdles.

Progress has been steady on multiple fronts. All 37 permits and approvals required ahead of tunneling have been obtained, out of 45 total. Key wins include a fully executed TDOT tunnel permit authorizing 25 miles of tunnel, unanimous airport authority approval for a Nashville International Airport station, and the city’s first residential station agreement serving downtown tower residents.

With MB1 already tunneling, MB2 now commissioned, and MB3 shipping in August, Nashville is becoming something of a live proving ground for scaled tunnel boring. The broader ambition is not limited to one city. The Boring Company’s stated goal is to make underground transportation a practical alternative to surface roads across major metro areas. Nashville is one of many cities, including a successful Las Vegas tunnel system, where that idea is being put to the test at real speed.
