This is a bounty to implement longitudinal support on the 2023-24 Hyundai Palisade and Kia Telluride. I will send the reward to the individual that completes the work, submits a Pull Request to comma’s openpilot repository on GitHub with a working route on the latest stock openpilot for verification, and written confirmations from at least 2 2023-24 Hyundai Palisade or Kia Telluride users.
