01

Makes driving chill

Currently, openpilot performs the functions of Adaptive Cruise Control (ACC) and Automated Lane Centering (ALC). openpilot can accelerate, brake automatically for other vehicles, and steer to follow the road/lane.

When openpilot is enabled, a driver monitoring system watches the driver and ensures the driver is attentive and ready to take over at all times.

When used correctly, these features reduce your workload as a driver, and can make long drives relaxing instead of tedious.

02

Connects to your car

openpilot works by connecting to your car's CAN network. Modern cars accept electronic steering, gas, and brake commands to allow for ADAS features. openpilot can use these commands to provide much better ADAS features than the car manufacturers can provide.

03

Modern machine learning

openpilot contains a state-of-the-art neural network that understands the road scene and predicts where to drive. This neural network has learned to drive by watching the millions of miles of driving data openpilot has recorded. This makes openpilot exceptionally good at nuanced situations such as driving in areas with faded lanelines, different countries, and more.

04

Open source and community supported

openpilot is developed by comma and by users like you. We welcome both pull requests and issues on GitHub. Bug fixes and new car ports are strongly encouraged. Check out the contributing docs.

@comma_ai for long-hauls. This thing drove me from Prague to Belgrade and back without issues. It can keep you in lanes almost all the time, change lanes, adapt the speed, stop & go in the traffic. It runs opensource openpilot which gets better every month.

@comma_ai I can honestly say the C3 is the single best purchase I’ve ever made. I can’t imagine driving without it now

@the_blueprint @Ebony84Rose Openpilot is better and far cheaper. Plus it works in way more cars. Assisted driving, for those of us that have used it, is much more relaxing. Especially on long drives over 3-4 hours. I love driving. But I feel more alert and rested when using assisted driving on long hauls.

@comma_ai and if it supports your car, buy it. It is well worth it.

@comma_ai I've been using openpilot for about 3 months now. Probably one of the best purchase decisions I've ever made. Great work @comma_ai team and @realGeorgeHotz

@comma_ai I have logged 3,780 miles with Openpilot engaged. Since I've had a Comma Two installed in my car, I have driven about 3,982 miles. This means my Openpilot engagement rate is 94.9% Now if we go by total miles driven since OWNING the car, the rate is (3780/5800 miles) = 65%

@comma_ai Comma 2 w/OpenPilot in our 2017 Subaru Impreza. Fascinating that a team of ~12 is able leverage available sensor suite that comes with almost any modern(2016+) car and make it better than the stock driver assist using a 2016 cellphone (LeEco LePro 3).

@comma_ai #CommaThree #OpenPilot0813 drove 99.5% hands free!!! Maybe 1 or 2 disengagements on my end. @realGeorgeHotz @aalleexx

@SnazzyQ I don't need a Tesla. I have OpenPilot, by @comma_ai. Definitely makes my driving more chill!

@comma_ai I recently did a 7,100 mile cross-country trip. The comma two running Openpilot made the long drives so relaxing and enjoyable!
