Researchers have designed a single-photon time-of-flight LiDAR system that can acquire a high-resolution 3D image of an object or scene up to 1 kilometer away. The new system could help enhance security, monitoring, and remote sensing by enabling detailed imaging even in challenging environmental conditions or when objects are obscured by foliage or camouflage netting.
Reason 1: humans can blink – a dirty camera can not.
I would hope teslas to have cameras in more than one direction, but maybe that was a too generous assumption.
