DIMM seems to go down slower lately.
Control: when to yield, without watching the face of the other driver, etc.
Edge cases: obeying a police officer, yielding to an ambulance, cooperating with other cars.

"Marcin Wichary, the lead typographer and designer at Medium, is obsessed with all things typeface, including typewriters. So when he chanced upon Museu de la Tècnica in a small Spanish town, nothing could have prepared him for what he found." https://twitter.com/i/moments/792044988842598400
Machine learning and data-driven methods require models with millions of parameters. Linguistic theories have traditionally not used such models.
A real neuron takes in the order of 10ms to integrate and fire to the next neuron. Many subconscious reactions take less than 1 sec, which leaves time to a chain of length less than 100. Note that those neurons are not strictly arranged in layers.
The human visual cortex has 10^12 synapses [1]. One popular 2015 deep learning net (ResNet 152-layers) used 10^12 FLOPs to classify objects in one image (but less weights.)
In terms of depth, we're there. In terms of breadth, it will take several years. But the brain does things very differently. For example, it has top-down signals during "prediction."
It is a good example of the superiority of deep learning.
One recent example: Reading Text in the Wild with Convolutional Neural Networks. Jaderberg et al. 2016. https://www.robots.ox.ac.uk/~vgg/publications/2016/Jaderberg...
1. They don't usually try to explain the specific activations in the hidden layers of the network. This is hard and depends on the specific trained net.
2. They can't guarantee a net's performance before experimenting with it.
