## What it is
sunnypilot is an open-source driver assistance system forked from comma.ai's openpilot, providing adaptive cruise control, automated lane centering, and driver monitoring for 350+ supported car models on comma hardware. It adds modified driving-assist behaviors such as modular assisted driving (MADS), enhanced speed control, and a driving model selector while adhering to openpilot's safety policy.

## Use cases
- add lane centering and adaptive cruise control to a supported car with a comma device
- decouple steering assist from cruise control using MADS
- switch between different driving models on a comma three or comma four
- get speed limit assistance using OpenStreetMap data and vision
- monitor a distracted or drowsy driver with camera-based driver monitoring
- remotely manage a comma device with sunnylink
- customize automatic lane change behavior with blind spot monitoring

## When to choose
- you own a comma three, 3X, or four device and a supported vehicle
- you want more customization and features than stock openpilot offers
- you want an open-source ADAS fork that follows comma.ai's safety policy

## When to avoid
- your car is not on the supported vehicle list
- you need a certified, production-grade autonomous driving system
- you are unwilling to accept alpha-software risks and data logging terms
