At least it is not as bad as in the philippines.
But then again, maybe filipinos got these bad habits from the spanish.
Worst example is Edsa, a huge 10-16 lane road that passes thru manila.
In the middle, they initially built chain fences. People cut holes thru them so they could jaywalk.
So they built overpasses/underpasses and then built a fence out of iron pipes.
And they posted signs that translate roughly into
"If you cross the street here, you will die"
People then went and got pry bars and broke holes into the fence, so they can still jaywalk, ironically right under the overpass.
I think the gov't has pretty much given up.
On the bright side maybe the people who get killed jay walking will have done it before they reproduce which will stop this bad habit.
On another topic, in between some of the lanes they have put huge concrete barriers, mainly to stop crazy drivers from weaving from one lane to another.
If u ever have to travel on edsa just try and keep your eyes closed
