From other technologies such as speech recognition, "how it works" seems to be - collect a lot of data and develop and train better and better models.

So tesla is collecting data, lots of it.

Additionally, there's the capitalism side of things - make sure you have a revenue stream to continue "develop and train"

So tesla has a revenue stream matched with the data collection.

So... Tesla is head and shoulders above Waymo in this.
