Argo also released a relatively massive 250GB dataset recently: https://www.argoverse.org/ The problem of Perception has a long road ahead at any of these companies and Argo is taking a very long position with this funding round. The headcount growth is rather worrisome but other than Aptiv there aren't many fleets that span multiple continents.
Taken out of the argoverse dataset description: - One dataset with 3D tracking annotations for 113 scenes - One dataset with 327,793 interesting vehicle trajectories extracted from over 1000 driving hours - Two high-definition (HD) maps with lane centerlines, traffic direction, ground height, and more
1000 driving hours is ok'ish for research (imho).
