Medium: How to write a car port for openpilot

"No safety relevant code runs on the EON. To use functional safety terminology, the EON functionality is considered Quality Management (QM). This means that any failure in delivering the desired output at the right time is perceived as bad quality and has no safety implications. You might be perplexed: the code running on the EON is responsible, for example, for determining the desired car trajectory and you might think that a bug in this algorithm might be a safety threat. But it’s not, openpilot is a Level 2 ADAS system and the driver must pay attention at all time! No ADAS system currently on the market has safety guarantees on perception or planning algorithms."
