Here are a couple of news articles that will help you know more about FSD...
The first news story is about the challenge of using Lidar and elimination of Radar to create a better FSD experience using only Vision: https://venturebeat.com/2021/07/03/tesla-ai-chief-explains-why-self-driving-cars-dont-need-lidar/
Second one is the new view coming to support FSD on the models that support it. Read all about it here: https://electrek.co/2021/07/06/elon-musk-tesla-ui-mind-of-car-view-fsd-computer/
Give yourself a pat on the back if you read through both articles and consider yourself more informed that you ever were before :-)
