I would love to have Waymo data. It looks like it's only available since September 2024 so I'll still need to use Tesla for the earlier period. More critically they don't publish disengagement data, only crash/injury. There are Waymo claims of things like 1 disengagement every 17,000 miles but I don't believe them without a precise definition for what this number represents.
