Is comma better than Toyota Safety Sense 2.5+?
comma may suit an owner who values its driver camera and open-source software path. TSS 2.5+ already offers substantial highway assistance, so assess the actual steering and speed-control behavior before deciding it is worth replacing.

What your factory system already does
TSS 2.5+ builds on Toyota’s lane-tracing and radar-cruise functions. Toyota’s precautions describe curve-speed reduction for this generation and TSS 3.0.
What could make comma worth it
Ask which daily annoyance you want to solve: attention prompts, lane position, or following behavior. comma’s camera-based monitoring is a clear design difference; a guaranteed smoother or safer drive is not established by these documents.
What to check for your car
Read the supported-car entry and speed-control notes. A change to openpilot steering does not by itself mean the car also switches away from Toyota’s cruise control.
Will comma retain every TSS feature exactly as before?
Do not assume identical behavior. openpilot changes particular control functions depending on the car. Review the exact integration and current official notes.
