Programming Autonomous self-driving cars with Carla and Python

description
Checking out Carla, which is an open source autonomous driving simulator. Carla creates a sort of open world with streets, other cars, pedestrians, weather, sensors, and more to help you to write logic to drive self-driving cars, coming with a Python API.
