The headline is "Tesla Autopilot Hits a Deer" which is as bland and unsensational as you can get while being true.

> A neural network mimics the way human brains work.

This is like saying a drawing of a circle mimics the way the sun works. NNs are vaguely inspired by a high-level neuron topology, but the similarities pretty much end there. Gradient descent and backpropogation don't take place in the brain at all, and we don't know enough about the brain to mimic the way it works.
