Requires Adaptive Cruise Control (ACC) & Lane Assist. Here is who controls what.
Official table checked Sep 2, 2026.
Simple answer
Steering
comma helps steer
Helps keep you centered in your lane. Stay ready to steer.
Gas and brakes
Your car’s cruise control handles gas and brakes
The normal setup keeps your car’s own speed and distance control. Test software differs; see the details below.
Your part
Watch the road. Stay ready to take over.
You remain responsible for steering and braking whenever needed.
Why steering alone can be worth it
You still get openpilot’s lane-centering assistance, even with factory cruise controlling gas and brakes. For highway driving, that can be the upgrade you want.
openpilot uses a driver-facing camera to check your attention instead of asking for regular nudges of the wheel. Attention alerts and requests to take over still matter: keep watching the road and be ready to steer or brake.
comma says openpilot can drive for hours without intervention. That describes a possibility, not a promise for this car or your route. Curves, weather, road conditions, and your car’s steering limits can require your help at any time.

On the road
In the standard release, openpilot steers while the car's factory adaptive cruise controls gas and brakes. Use the car's normal cruise controls for speed and following distance.
The stable release cannot use Experimental Mode on this car. Comma lists alpha openpilot gas and brake control, but its toggle is limited to non-release branches such as nightly-dev. Fork behavior is separate and must be checked with that project.
Chestnut gives comma four more computing power for larger driving models. The connection to the car still decides whether openpilot can send steering, gas, and brake commands. What Chestnut changes
A car may use radar, cameras, or both to see traffic. That is separate from who sends gas and brake commands. The official row does not name the sensor for this car, so CommaGuide does not guess.
Quick answers
Yes. The official table lists openpilot steering at all speeds.
Your car’s cruise control handles gas and brakes in the standard openpilot release. The normal setup keeps your car’s own speed and distance control. Test software differs; see the details below.
It needs the alpha gas and brake setting, which comma does not show in stable releases.
No. Chestnut provides more compute for a larger driving model. It does not add steering, accelerator, or brake access to the car.
