Lane Centering
Continuous steering assistance keeps the vehicle centered in the lane instead of waiting until it drifts toward the edge.
LATERAL ASSISTANCE
UPGRADE THE CAR YOU ALREADY OWN
MAKE YOUR CAR
DRIVE LIKE IT
CAME FROM THE FUTURE.
If your vehicle is compatible, we can help turn its factory steering and cruise-control hardware into a much more capable driver-assistance experience: lane centering, adaptive cruise, driver monitoring, and supported hands-off / eyes-on highway assistance — without buying a new car.

Why the wording matters: NHTSA distinguishes Level 2 driver-assistance systems from automated driving. Systems that combine lane centering and adaptive cruise still require the driver to remain engaged and alert. This website uses the memorable domain name without misrepresenting the actual driving responsibility.
What the upgrade can do on compatible vehicles
YOUR FACTORY CAR.
A MUCH BETTER COPILOT.
Current openpilot documentation describes the system as an open-source driver-assistance system that can provide adaptive cruise control, automated lane centering, driver monitoring, and related assistance on supported makes, models, years, and configurations.
◉
Adaptive Cruise
On supported configurations, the system manages speed and following distance and can control acceleration and braking within the supported operating envelope.
LONGITUDINAL ASSISTANCE
👁
Driver Monitoring
Camera-based monitoring is designed to detect distraction or sleepiness while assistance is engaged. The driver still supervises the road.
EYES-ON SUPERVISION
⇄
Lane Change Assistance
Current comma product materials list lane-change assistance as part of the supported openpilot driving experience.
SUPPORTED VEHICLES
Compatibility before installation
DO NOT BUY HARDWARE UNTIL WE CHECK THE CAR.
Compatibility depends on the exact make, model, year, trim, factory driver-assistance package, and sometimes the market the vehicle was sold in. The quick checker below includes a small set of currently verified examples. Anything else goes to manual review against the official supported-car list.
READY FOR INPUT
Enter the exact vehicle.
This checker is intentionally conservative. A “likely match” is still verified against the current official support list before installation.
Verified examples from the current comma site
THE SUPPORT LIST IS ALREADY
MUCH BIGGER THAN MOST PEOPLE THINK.
These are only sample vehicles surfaced by the current comma homepage and vehicle pages, not the full compatibility list.
Installation workflow
THE HARDWARE IS SMALL.
THE COMPATIBILITY CHECK IS THE IMPORTANT PART.
comma’s current setup guide labels the core installation as a 15-minute, five-step process. A professional service should add pre-check, clean cable routing, software setup, calibration, and a supervised road test rather than treating “plug it in” as the whole job.
Verify the exact vehicle
Confirm make, model, year, trim, factory driver-assistance package, harness, and current supported-car status.
BEFORE APPOINTMENT
Install the car-specific harness
Connect the supported harness at the factory camera / ADAS interface and route the required cable cleanly.
VEHICLE-SPECIFIC
Mount + power the device
Position the device correctly on the windshield and complete required power / OBD connections for the supported setup.
CORE SETUP
Software + calibration
Install the current supported software, select the correct configuration, and allow the system to calibrate as required.
VERIFY BEFORE ROAD TEST
Supervised road test
Confirm engagement, lane-centering behavior, cruise operation, driver monitoring, alerts, and safe disengagement with the owner.
OWNER HANDOFF
Straightforward supported installs may physically fit within a roughly 15–30 minute service target, but time can vary with vehicle trim, harness routing, prior modifications, software state, calibration, troubleshooting, or the need to verify compatibility.
Before
Factory assistance that only helps in pieces.
Many compatible cars already have the steering, radar, camera, braking, or cruise hardware needed for modern driver assistance, but the stock experience can be more limited or less integrated.
○Factory lane-keeping / lane-departure behavior
○Factory adaptive cruise behavior
○Separate systems with manufacturer-specific limits
○No assumption that every trim/year is compatible
After · compatible vehicle
One integrated driver-assistance experience.
openpilot can replace or augment parts of the supported factory driver-assistance stack with continuous lane centering, adaptive cruise behavior, driver monitoring, and supported lane-change assistance.
✓Automated lane centering while engaged
✓Adaptive speed / following behavior on supported configurations
✓Camera-based driver monitoring
✓Software updates and evolving supported capabilities
The site name is catchy. The safety language has to be precise.
THIS DOES NOT MAKE
THE DRIVER OPTIONAL.
NHTSA describes combined lane-centering and adaptive-cruise systems as Level 2 driving assistance, where the driver must remain engaged and alert. The current comma homepage similarly markets a hands-off, eyes-on experience rather than driverless operation.
01
Driver remains responsible
Eyes on the road, ready to take over, and responsible for complying with traffic laws and system limitations.
02
Compatibility is exact
Year, trim, factory equipment, market and software support matter. “Has lane keep” is not enough by itself.
03
Factory safety systems matter
System behavior varies by car. Some supported configurations replace factory lateral or longitudinal control while preserving other safety features; exact notes must be checked per vehicle.
04
No affiliation claim
This installation-service concept is independent. It should not claim to be comma.ai or an authorized installer unless that relationship is formally established.
Book the compatibility check first
THE APPOINTMENT STARTS WITH YOUR VIN, NOT YOUR CREDIT CARD.
Send the exact vehicle information and current driver-assistance equipment. The installer can verify the official support notes and the required harness before confirming an installation.
Common questions
WHAT “SELF-DRIVING”
MEANS HERE.
No. The domain is the brand name. The underlying supported technology is advanced driver assistance. The driver remains responsible, attentive, and ready to intervene.
On supported vehicles openpilot can perform automated lane centering and adaptive cruise-control functions; exact longitudinal control and factory-system interaction varies by vehicle.
comma currently describes its core setup as about 15 minutes. A service appointment may target roughly 15–30 minutes for a straightforward supported vehicle, but compatibility checks, routing, software, calibration, prior modifications or troubleshooting can extend the appointment.
No. Those features are a useful clue, but official support depends on the exact vehicle and configuration. Always verify the current supported-car notes.
The manufacturer provides a setup guide and sells car-specific hardware. This service exists for owners who want compatibility help, clean installation, software setup, calibration guidance, and a supervised handoff.
No. This is an independent installation-service concept. Product compatibility should be verified against the current official comma/openpilot documentation.
