Human drivers are also not equipped with a LIDAR. We rely on stereo-vision combined with a couple of low-tech instruments (rearview mirror, left and right side mirrors and looking-over-shoulder to achieve approx 250-300 degrees view of field) to navigate the road in a vehicle. If you extrapolate the current state of AI and treat 10-20 in-car cameras + radar as the equivalent of what a human brings to the table then I fail to see why Tesla has painted itself in a corner.
