As far as I’ve seen, any system would be additive. If it has lidar, it would also have cameras and radar. So that you get the best of all the technologies (e.g cameras are the only only of the three that can follow lane markings)

Did he have lidar removed? I thought it was radar. I didn’t think any Tesla vehicle ever took on the cost of lidar.

Besides that, in the fog and rain tests a human likely would have killed a kid anyway, and why settle for human limitations when you could be safer?

We absolutely should also have lidar or analogous tech as part of a solution here, even if cameras did manage to get to human level safety.
