Waymo has ~40 million miles of test data. Tesla has ~4B miles. But for training both quantity and quality are important. Tesla only uploads excerpts and metadata for its 4B miles, and it's video only. Waymo can fully analyze all 40M miles, and it's much richer, with LIDAR and other sensors.

My feeling is that Waymo has the data advantage.

You can also just buy camera data from other OEMs, not to mention the vast amounts available from public sources like YouTube or Google maps vehicles that are accessible to them if they really care. The vast, vast majority of that data is uninteresting though. It's not much better than simulation data, which Waymo has many tens of billions of miles worth.

I’ll trust Waymo’s 40 million over Tesla’s 4B any day. You can make something work most of the times with our vision. But when there is no one to man the car, most of the times isn’t good enough
