guatemala two step

There is a dance I do  every  day  that  I  call  the  Guatemala Two Step.  This is the dance I do to avoid getting killed  by the traffic. The dance starts with walking in the  street  due to all manner of objects on the sidewalk  such  as dogs, car parts ,  unmentionable  discards, and people .    You take one step forward  in the street, see  a car barreling towards  you,  take a quick step to right,   walk a few steps forward , and step back to the left  when the car has passed.  This dance step is  repeated  multiple  times until  you make it to the next street.   Drivers here find  pedestrians  to be an annoyance and will virtually  never yield  to a pedestrian. You have to be quick here  or your next partner will be in cemetery .   The picture today is a  footbridge  near  my house  that  I  have  never  seen used .   I wonder why?
