Since the website is not clear, here is what it is. Comma Two is an aftermarket dash cam that adds features like adaptive cruise control, automatic lane centering, and forward collision warning to cars using open source software. It uses a combination of the dash cam and the vehicle’s built in radar to accomplish this. It is able to control the car and receive its radar data by connecting to the vehicle’s OBD port. The unit is $1000 and also requires the purchase of a vehicle specific harness for $200. A list of compatible vehicles can be found here: https://comma.ai/vehicles https://comma.ai/vehicles The source code that performs the driver assist functionality has to be loaded by the user and is available here: https://github.com/commaai/openpilot https://github.com/commaai/openpilot There’s also a “prime” subscription which pays for cell service on an included SIM card and allows you to see video footage or location data from your vehicle remotely.
