The seconds after a collision are pure misery — hands shaking, glovebox open, paperwork you can’t find, and a stranger you’re somehow supposed to trade details with. GM’s pitch? Let the cars handle it.

The automaker has filed a patent application for a vehicle-to-vehicle system that lets two crashed cars recognize each other and swap driver information on their own, 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, was submitted to the United States Patent and Trademark Office on November 7, 2024, and published on June 16, 2026. It credits four Canadian engineers as the inventors: 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, the system lets the cars do the talking. Two vehicles caught in the same crash recognize one another and share the relevant details themselves. That’s the whole pitch, aimed squarely at the part of a wreck most people dread.

How it would work
The clever bit is that it barely needs new hardware. The system leans on a collision detection module tied to a spread of onboard sensors and a vehicle database. Per the filing, those sensors could include LiDAR, radar, and visual cameras — the same gear modern cars already carry for driver assist and safety. GM is describing hardware many vehicles already own, just pointed at a new job.
When it senses a potential collision, it works out whether another vehicle was involved. It can use image processing to confirm a nearby object really is a car, and check make, model, and color — because matching the right two vehicles is the entire point. Grab the wrong car or misread the scene, and the system creates more problems than it solves.
Once a collision is detected, the car can broadcast a collision message to others nearby. If another vehicle fires back a matching message, both confirm they were in the same event. The filing describes several channels for passing these along — vehicle-to-vehicle, vehicle-to-infrastructure, vehicle-to-people, and cellular. So the car isn’t shouting into the void; it’s 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 — which may include the driver’s insurance, license, and vehicle registration, plus the time and location of the crash. The driver is then prompted to send the report and can view the other vehicle’s information once it’s decrypted.
That encryption isn’t a throwaway detail. The patent describes the automatic exchange of some of the most sensitive paperwork a person carries, and it wraps that exchange rather than blasting it in the open. That’s a meaningful design choice — anyone who’s 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. Crash aftermath is when people are rattled, sometimes hurt, and rarely thinking clearly — and that’s exactly when they’re expected to gather accurate information from another shaken driver. Automating the data exchange could make that moment safer and faster, and cut down on the disputes that come from missing or wrong information later.
There’s 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’s 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 handles 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.
