Tesla fanboys seem to frequently forget the following facts:

* People using lidar also use deep learning.

* Lidar and HD maps are totally orthogonal concepts with nothing to do with each other. Lidar helps you avoid running into trucks without HD maps. Camera-based methods can use HD maps too.

* Lidars are less affected by rain and snow than cameras are (thanks to larger optical aperture, multiple returns, and faster "shutter speed" due to nanosecond pulses rather than 1/30 s exposures).

* Tesla's "big data" is not more effective than a concerted active learning data collection campaign with a moderate-sized fleet.

* HD maps are very cheap to create.

* Lidars may in fact be cheaper than the GPU you're going to need to run your monocular depth network, while being more accurate and more robust.

FWIW, you can just buy HD Maps: https://www.tomtom.com/products/hd-map/

Provided any concurrent can build a team of people with as much focus and ressourced as tesla. Even if equal, big data from real drivers beats everything else.
