Few moments behind the wheel are more stressful than the seconds right after a collision. GM apparently thinks your car should handle the awkward part for you. The automaker has filed a patent application for a system that would let two crashed vehicles automatically identify each other and exchange driver information, with no roadside scramble for paperwork required.

What GM actually filed
Here is what is on record. The application carries patent number US 12,657,968 B2 and was submitted to the United States Patent and Trademark Office on November 7, 2024. It was published on June 16, 2026, and credits four Canadian engineers as the inventors. Those names are Mohammad Naserian, Daniel Xie, Patrick Giancarlo Gabriel DiGioacchino, and Utkarsh Saini.
The idea at the center of the filing is a vehicle-to-vehicle communication system built around what happens after impact. Instead of forcing drivers to climb out, dig through a glovebox, and trade insurance cards on the shoulder of a road, the system would let the cars do the talking. Two vehicles caught up in the same crash would recognize one another and share the relevant details on their own. That is the whole pitch, and it is aimed squarely at the part of a wreck most people dread.

How it would work
The system leans on a collision detection module tied to a spread of onboard sensors and a vehicle database. According to the filing, those sensors could include LiDAR, radar, and visual cameras, along with other equipment that already lives in modern cars for driver assist and safety features. In other words, GM is describing hardware that many vehicles are already carrying, just pointed at a new job.
When the system senses a potential collision, it goes to work figuring out whether another vehicle was part of it. It can use image processing to confirm that a nearby object is in fact a car, and it can check details such as make, model, and color. That detail matters, because matching the right two vehicles is the entire point. A system that grabs the wrong car or misreads the scene would create more problems than it solves.
Once a collision is detected, the vehicle can broadcast a collision message to others nearby. If another car sends back a matching collision message, the system can confirm that both vehicles were involved in the same event. The filing describes several ways to pass these messages around, including vehicle-to-vehicle, vehicle-to-infrastructure, vehicle-to-people, and cellular-based communication. So the car is not just shouting into the void, it is using multiple channels to make sure the message lands.
The part drivers will care about
This is where the story turns toward your wallet and your license. After the two vehicles are matched, the system can exchange encrypted collision reports between them. Those reports may include the driver’s insurance, license, and vehicle registration, plus the time and location of the crash and other relevant information. The driver would then be prompted to send the report, and could view the other vehicle’s information once it is decrypted.
The encryption piece is not a throwaway detail. The patent is describing the automatic exchange of some of the most sensitive paperwork a person carries, and it is wrapping that exchange in encryption rather than blasting it in the open. That is a meaningful design choice. Anyone who has ever worried about handing a stranger their personal details on the side of a highway can see why it belongs in the system from the start.
Why this matters beyond one fender bender
For drivers, the appeal is obvious. The aftermath of a crash is when people are rattled, sometimes hurt, and rarely thinking clearly, and that is exactly when they are expected to gather accurate information from another shaken driver. A system that handles the data exchange automatically could make that moment safer and faster, and it could cut down on the disputes that come from missing or wrong information later.
There is a bigger thread here too. A patent built around LiDAR, radar, and cameras working together to read a crash scene is a reminder of how much sensing power is already packed into newer vehicles. GM is essentially proposing to take hardware bought for crash avoidance and put it to work on crash paperwork. That is a clever reuse, and it hints at where connected-car features may keep heading.
One important reminder applies to all of this. A patent application is a description of an idea, not a promise of a product, and plenty of filings never reach a showroom. Still, the direction is clear enough. GM is sketching a future where the car you crash does the part of the job you least want to do, and that alone tells you something about where the industry thinks the next round of convenience features is going.
