Is comma better than Toyota Safety Sense P?
Worth exploring if your supported Toyota has lane-departure assistance and you want active lane centering. Start with the exact car; TSS-P alone does not prove compatibility.

What your factory system already does
TSS-P includes radar cruise and Lane Departure Alert with steering assistance on applicable vehicles. Toyota’s generation guide distinguishes this from the Lane Tracing Assist found in later systems.
What could make comma worth it
The useful comparison is a brief correction near a lane edge versus openpilot’s lane-centering role. That is a practical reason to investigate comma for a supported older Toyota, without replacing the entire car.
What to check for your car
Confirm the exact year and required Toyota package, speed-control implementation, minimum steering speed and any additional parts. A TSS-C car is not a TSS-P car.
Does comma upgrade TSS-P to TSS 3.0?
No. It adds a separate driver-assistance system on a supported configuration; it does not install Toyota’s newer sensors or full safety package.
