For a Tesla, the estimates are around $2K. For a Waymo, the same estimates are ~$25K (down from $125K!!!). There's not a clear timeline for Waymo-style kit at a price consumers can afford and in a form factor they'd accept.
(FWIW, the business story for Waymo has never been about its hardware making its way to consumers. It's always been about whether Waymo continues to run its own taxi service or leases out hardware and operations to other taxi businesses).
