This is an estimation for the self-driving hardware cost (computers, LIDAR, sensors). It does not include the base car price, as it can be easily optimized down to almost nothing (sub $10k).

The price is somewhat of a guess, several years ago, the hardware in Waymo was priced at $130k by Munro&Associates. But since then the cost of the LIDAR sensors fell by 90% or so, reducing the main expense.

And Baidu has cars on the road that cost $30k for the _entire_ car. So presumably, so even a couple of pricier sensors won't affect the estimate too much.
