If you had multiple cameras for stereoscopic vision. Couldn't you figure out the depth data vision only without lidar? I'm sure there was a good reason Tesla didn't go with a stereoscopic camera system (at least front facing) from the get-go.. they already have 3 cameras up there with 3 FOVs. Could add another camera there in a stereo setup for depth data.
