Step 1 - find an object detection model that's not used in self-driving cars
Step 2 - show that the model detects dark-skinned pedestrians 5% less often than light-skinned pedestrians
Step 3 - write a clickbait title implying that self-driving cars will run down dark-skinned pedestrians with precisely zero evidence
Step 4 - post the article on HN with an even more inflammatory title than the actual article
