Add FSD to a Lexus RC? Here's what works

Tesla's FSD stays on Teslas. But your RC can steer itself and follow traffic with one device plugged in behind the mirror.

Yes. Your RC is on comma's list.

comma lists the 2018–2023 RC. Every trim qualifies. openpilot controls the gas and brakes on some years; the car's own cruise does it on others. Steering works all the way down to a stop.

Steers itself in the lane

Continuous centring on highways and most roads, not a nudge back from the line.

Follows the car ahead

Sets the gap and speed, slows for traffic, and stops and goes where listed.

You stay in charge

A driver camera checks your eyes. No city turns, no naps, no FSD claims.

How to add it to your RC

Four steps. No wiring cut, no dealer visit.

  1. 1

    Confirm your year and trim

    Open your exact RC below. Trim names decide whether the car has the cruise and camera openpilot needs.

  2. 2

    Order the comma four with the Toyota A connector

    Pick your car in comma's shop and the right harness is added. Nothing else is required.

  3. 3

    Mount it behind the mirror

    Stick the mount high and centred, plug the harness in at the camera, and route one cable. About fifteen minutes.

  4. 4

    Drive a few minutes, then engage

    It calibrates on your first drive. Then press your cruise button and the RC takes the lane.

    What the first drive is like

Every RC comma lists

Open your year for the exact trim, harness, and what controls speed.

Lexus Safety System+ versus openpilot

Lane Tracing Assist centres the lane with radar cruise on, hands on the wheel. openpilot adds the same on older Lexus models and works down to a stop.

Questions RC owners ask

Is this Tesla FSD for a RC?

No. FSD is Tesla software for Tesla cars. This is openpilot, an open-source driver-assist system that steers and follows traffic on your RC. You watch the road and stay responsible.

Which Lexus RC years work?

comma lists the 2018–2023 RC. Open the exact year below to confirm your trim.

Do I keep Lexus Safety System+?

Yes. The harness sits between the car and its camera, and your factory safety features keep working. Unplug it and the car is stock again.

Does it handle stop-and-go traffic?

Yes on the listed RC years. It slows to a stop behind traffic and moves off again on its own.

Is there a subscription?

No. The device and the software are a one-time purchase. comma prime is an optional extra for remote access and longer drive storage.

Do I need to keep my hands on the wheel?

Not constantly. A small camera watches that your eyes stay on the road, and openpilot warns you and stops steering if they do not.
