LEAD: Minimizing Learner–Expert Asymmetry in End-to-End Driving

Project Page | Paper | Code

Official CARLA dataset accompanies our paper LEAD: Minimizing Learner–Expert Asymmetry in End-to-End Driving.

We release the complete pipeline required to achieve state-of-the-art closed-loop performance on the Bench2Drive benchmark. Built around the CARLA simulator, the stack features a data-centric design with:

• Extensive visualization suite and runtime type validation for easier debugging.
• Optimized storage format, packs 72 hours of driving in ~200GB.
• Native support for NAVSIM and Waymo Vision-based E2E and extending those benchmarks through closed-loop simulation and synthetic data for additional supervision during training.

Format

Each route is stored as a sequence of synchronized frames. All sensor modalities are ego-centric and time-aligned.
In addition to the nominal sensor suite, we provide a second, perturbated sensor stack corresponding to a counterfactual ego state used for recovery supervision.

Download

You can either download a single route (useful for quick inspection / debugging) or clone the full dataset via Git LFS and unzip all routes.

Note: Download the dataset after setting up the lead repository.

Option 1: Download a single route

bash scripts/download_one_route.sh

Option 2: Download all routes (Git LFS)

Clone the dataset repository directly into the expected directory:

git lfs install
git clone https://huggingface.co/datasets/ln2697/lead_carla data/carla_leaderboard2/zip

Unzip routes

Run

bash scripts/unzip_routes.sh
