This is super cool, especially how it is done as a side project. It's resourceful using a game as the physics simulator. I wonder how it compares to Microsoft's [1] and Udacity's [2] implementation.

Thanks for the links! Really cool. Know of any open source Kerbel Space Program type sim?

  Not as fancy as the other ones but Nasa has a toolbox called trick[1]. This is completely numerical based and allows you to do all the necessary numerical calculations easily. [1] https://github.com/nasa/trick https://github.com/nasa/trick

I think a fair comparison would be to AirSim [1] and Carla [3]. These are much more mature projects and are similar to Autodrome in a lot of ways. As far as I know Udacity's simulator is done their class and it's not being actively developed. + Both [1] and [3] have much fewer assets (like 3D models of houses, factories, bridges, cars, trucks, and so on) you'd have to buy them on the Unreal/Unity model marketplace and it still wouldn't be enough. Autodrome can take advantage of almost entire Europe and a third of USA at 1:20 scale. + Autodrome has a sparse map representation that is really easy to randomly fuzz. I.e. it's easy to shift a segment of the road a little bit and see how the algorithm would react to the fuzzed scenario. I believe this is only way how to achieve robust agents and effectively prevent testing on the training set. - Biggest disadvantage of Autodrome is a lack of access to in-game dynamic NPCs (like other trucks, cars or pedestrians). As far as I know there's no API for this. Without help (or a lot of very fragile memory hacking) from the developers of the game this feature is very hard to achieve and both [1] and [3] already have it.

  Thank you for the detailed response! Is there any thoughts on ground truth segmantic segmentation camera view? Simulated lidar data would be super awesome too.

    Both are also not easy like the dynamic NPCs. I think Carla [3] supports both raytraced lidar and segmented rendering now so this is another minus “-“ point.
