We designed these challenges around real problems we've faced while building and shipping openpilot. We hope you enjoy them. * Submit your solution here * Multiple submissions are allowed * Non-competitive scores will not be published * 👑 is a cash prize winner * is an employee or intern score * Active challenges are still expected to be difficult * Archived challenges are largely solved problems If you find these fun and score well, you'll probably be a good fit for a job here.
