I don't think you want to download the data directly to your machine since its 575GB. They posted a notebook that shows how to download the data but you need a Google Cloud account for that and for me it only worked when I added billing information (but I think the actual data download fees are on their side).

Unfortunately it seems like that's the only way to get the files

Edit:

Just found out you can download the data directly with a link even without account. Just go to https://storage.googleapis.com/brb-traffic/ to see a XML of all the files and then construct a link like so: https://storage.googleapis.com/brb-traffic/[key] (example: https://storage.googleapis.com/brb-traffic/normanniles1/normanniles1_2025-10-20-12-11-45.mp4 ). You can simply write a script that parses the XML and loops through the files to download them
