I don't think Tesla use lidars, and I don't think the small Quanergy lidars are shipping yet. PX2 isn't widely available but you can pick up a TX1 which is pretty powerful, if you need something small/low power but still fast enough for your own robot. Runs Ubuntu and CUDA so you can run the same deep learning frameworks (and possibly models, if you optimise them) as on your desktop
