I've had this device for over 15 months and it's been a game-changer for my 120 mile RT commute to San Diego 3 days per week. I use it on a 2022 Corolla Hybrid which is one of the most compatible cars with Comma (full start/stop). I've also used it on the occasional trip up to Northern California and it's been a god-send. I occasionally use it on my wife's 2019 Pilot as well as I bought an extra harness and power supply. For a long-distance commute, it really does take the edge off of driving. I find myself arriving at home and at work so much more relaxed. The benefit of my commute is it's mostly 50 miles of open driving on the I-5. I sit in the 3rd lane at 70mph and just let it do it's thing. A bit of traffic in the Carlsbad area is easily handled and cannot recommend this device enough.

Ya this isn't a product you wait for... Every freeway mile without it could be sooo much better. I bought at $3k and not one part of me wishes I waited.

Description:
Comma.ai is having a July 4th Sale on the highly sought-after Comma 3X, a custom hardware device designed to run openpilot, their open-source advanced driver-assistance system. Get the Comma 3X for just $799 (originally $999), plus a vehicle harness for $99 (required to connect the Comma 3X to your car). That's a total of $898 for the full setup, making it an incredible value for an advanced ADAS solution.

This is a significant price drop for the Comma 3X, which previously sold for $999 or more, and now includes the harness at a special discounted price! Shipping is free on all orders (US only; international shipping is a $30 flat rate).

Key Features of Comma 3X:

Qualcomm Snapdragon 845 processor

2160x1080 OLED Display

128GB Internal Storage

WiFi/LTE/High Precision GPS Connectivity

IR LED Interior Night Vision Monitoring

CAN FD Vehicles Enabled

3x 1080p Cameras w/ 140 dB of Dynamic Range; Dual-Cam 360 Vision & Narrow Cam

OBD-C Port (USB-C w/ CAN) + USB 3.1 Gen 2 Port

Includes 1-year hardware warranty against defects.

Deal Details:

Product: Comma 3X

Price: $799 (Device) + $99 (Vehicle Harness) = $898 total

Original Price (Comma 3X): $999 (device alone was often more, and the harness was separate)

Savings: Over $100 off previous sale prices and regular pricing.

Store: Comma.ai (Official Website)

Shipping: FREE Ground Shipping (US orders). International shipping is $30 flat rate. Upgrade to UPS 2-Day Air is available for an additional $25.

Compatibility: Works with over 275+ cars. Ensure you select your eligible harness from the drop-down menu on the product page. [Check Compatibility List Here: https://comma.ai/vehicles]

Trial Period: Includes 30-day money-back trial.

Offer Valid: While promotional price/supplies last.

Why this is a good deal:

Great Price for Advanced Tech: A competitive price for cutting-edge open-source ADAS hardware.

Advanced ADAS: Transforms your compatible vehicle with advanced driver-assistance features like automated lane centering, adaptive cruise control, and 360° vision.

Open-Source & Continuously Improving: openpilot receives regular over-the-air (OTA) updates, constantly enhancing its capabilities.

It's going to keep dropping in price, the market is super niche.

Probably relatively slowly... Debate will be how much time do you want to wait while not being able to use the product.

Oh wow, this thing can be bought now?

Check out the video from 9 years ago from the original idea ... ;-)

it's been on the market for years.

Hotz isn't even involved with it anymore.

Quote from SiavashS :
comparing comma ai with Tesla's FSD is very misleading. Given how poorly Tesla's FSD acts at times, I'm not sure if it really worths spending so much money just to get a better ADAS than what my car already has.
What is your car make and model? Not sure if you are aware of the features that Openpilot or Sunnypilot or frog pilot (advanced driver assistance system) etc offers. I am curious to know which car that performs better than stock offerings excluding Tesla FSD

Anyone using in the 22 Model 3? They have a harness for the Tesla. It's cheaper than FSD with 80% function I see

Hello Neighbour, how did you install it in your car. was it DIY? Does installing this voids car warranty? i have a honda accord 2020 and it has full honda warranty till 2028. i am thinking if getting this

I've been using Comma for over four years on my then new Prius. Toyota, during free service work, never asked questions. This is excellent for long trips. Before Comma I'd feel tired and restless after a long drive. Now I take day long trips and feel fine. This is not for urban driving, but is perfect for mindless open roads. I even engage when doing short drives. I absolutely would buy again without a second thought.
