## What it is
A Unity-based self-driving car simulator built for Udacity's Self-Driving Car Nanodegree, used to train cars to navigate road courses with deep learning. The master branch is deprecated, with maintained forks on Unity 2019/2020 branches.

## Use cases
- train a neural network to drive a car in a simulator
- collect driving data for behavioral cloning projects
- practice deep learning for autonomous vehicles
- simulate road courses for a self-driving car nanodegree project
- test steering models against a virtual track

## When to choose
- you are following Udacity's self-driving car curriculum
- you need a lightweight Unity simulator for behavioral cloning experiments
- you want precompiled simulator builds for Linux, Mac, or Windows

## When to avoid
- you need an actively maintained or production-grade driving simulator
- you require modern physics, sensors, or CARLA-style fidelity
- you are not working with the deprecated Udacity course projects

## Facets
- artifact type: application
- maturity: abandoned
- function: simulation, machine-learning, deep-learning, computer-vision
- domain: simulation, autonomous-vehicles, machine-learning, education, gaming-tools
- platform: windows, cross-platform
- tags: self-driving-car, unity, behavioral-cloning, nanodegree, deprecated, training-simulator, linux, macos
