Tesla CEO Elon Musk has said that lidar sensors are a “crutch” for autonomous vehicles. But his company has bought so many from Luminar that Tesla is now the lidar-maker’s top customer.

Tesla accounted for “more than 10%” of Luminar’s revenue in the first quarter of 2024, or a little more than $2 million, the lidar-maker revealed Tuesday in its first-quarter earnings report.
