US probes Tesla's Full Self-Driving software after fatal crash

> The collision happened because the sun was in the Tesla driver's eyes, so the Tesla driver was not charged, said Raul Garcia, public information officer for the department.

Am I missing something or is this the gross miscarriage of justice that it sounds like? The driver could afford a $40k vehicle but not $20 polarized shades from Amazon? Negligence is negligence.

Not to mention that when you can't see, you slow down? Does the self-driving system do that sufficiently in low visibility? Clearly not if it hit a pedestrian with enough force to kill them.

The article mentions that Tesla's only use cameras in their system and Musk believes they are enough, because humans only use their eyes. Well firstly, don't you want self-driving systems to be better than humans? Secondly, humans don't just respond to visual cues as a computer would. We also hear and respond to feelings, like the sudden surge of anxiety or fear as our visibility is suddenly reduced at high speed.

I think one of the reasons they focus only on vision is basically the entire transportation infra is designed using human eyes a primary way to channel information.

Useful information for driving are communicated through images in form of road signs, traffic signals etc.
