We all know that Red Sector is an insanely overcrowded place with incredibly low average income. This, combined with relatively high price of cars makes me think that the Mix is pedestrian dominant to an extreme level. And because of this I would expect that traffic in the mix would be terrible.
I can easily imagine cars having to frequently slow down as crowds of people cross the street without notice. I also think that, given the low level of legal enforcement in the mix, traffic laws are more suggestions then hard rules. The crowded conditions might also encourage smaller vehicles like motorcycles and pedicabs.
I simply envision it as a more extreme version of what I experienced in Ahmedabad, India and similar cities (for those who have the opportunity to visit such places). Cars and cabs zooming through the streets just doesn't feel right to me in a place like the mix.
