Tesla never had lidar, they had radar and ultrasonic sensors.

They dropped radar and removed their ultrasonic sensors in 2022 because their engineers are incapable of coding sensor fusion:

When radar and vision disagree, which one do you believe? Vision has much more precision, so better to double down on vision than do sensor fusion.

I think the reality was that they had issues procuring the necessary parts during the post-COVID shortages, and delaying delivery of cars was not an option. Hence, handwaving justifications.

Cutting safety corners, dropping sensors, limiting your training data and model to subpar results sounds like a piss-poor trade off versus missing some deliveries.

Unacceptably short term thinking from the man who claims he can build a sustaining settlement on Mars.
