I've already shared a couple of videos demonstrating how I test the PionEar sensor and its machine-learning model performance in a car. I've captured some nice footage of it detecting ambulance sirens. Before I actually get in the car and spend time driving, I first run tests using a PC and YouTube. This initial testing provides valuable insights into whether it's worth testing in a real-world environment. Additionally, I want to showcase that the current machine-learning model is quite resilient to various traffic noises.
