That style of "urban assault" is pretty much accepted practice there, and in most Central and South American countries. In Guatemala, for instance, they are allowed to cut stopped traffic to the front. They split lanes on moving traffic, which is illegal, but not really enforced. One cool part of the law in Guatemala, if you run over a biker, you have to pay thier medical bills, and replace thier wages while they recover. The constables enforce this. All anyone has to do is report they are not getting paid, and the constable in the responsible party's district will go by and give them 24 hours to pay up, or they confiscate thier private property and sell it to pay the debt! Of course the only reason this works is, the Constable walks his jurisdiction every day! Imagine that, accessable government. They are well taken care of by the citezenry, as a general rule. Some are on the take, and that is troublesome, but most places, it works.
I've been as far down as Chile, and the traffic stuff is pretty much the same. El Salvador used to offer the death penalty for drunk driving offenses! It was a deterrent, I'm told!
Bottom line, you have to cover your own butt out there. Nobody else cares about you.
And you can put your foot down for a "save" with an athletic shoe on without loosing the foot, but you just might yank the sole right off! Ask me how I know.
