Hotz has mentioned that the training code is not public because it wouldn't benefit anyone apart from those that are trying to wholesale copy the entire project. You can see model architecture and gleam insight from the decisions that they made. You can run simulations with the model and replay scenarios. You can add support for currently unsupported vehicles. Dev tools let you see signals generated. There's a lot of stuff you can do. But what they don't let you do is easily clone the report, throw a few million in compute and repackage what they had built. I think it's a reasonable restriction.
