# SimLingo CARLA Dataset (Raw, 4Hz)
Raw driving data from CARLA simulator. No transformations or derived fields - all original measurements preserved as-is.

- **Scale**: 228,757 frames (23 shards)
- **Frame Rate**: 4 FPS
- **Resolution**: 1024x512 RGB
- **Routes**: Complete driving episodes (routes never split across shards)

## Usage
```python
from datasets import load_dataset
import json
ds = load_dataset("TESS-Computer/carla-simlingo-raw", split="train")
sample = ds[0]
print(sample['route_id'])
print(sample['steer'], sample['throttle'], sample['brake'])
print(sample['speed'])
# Parse JSON fields
pos = json.loads(sample['pos_global'])
boxes = json.loads(sample['boxes']) if sample['boxes'] else []
```
