The drivers here where I live, are mostly ignorant and bad drivers, many get their driving licence (should I say) not in the normal way as we know normal, so many are driving with no real experience.
Expect to be overtaken on either side, do not stop when pedestrians are on the zebra crossing, because they have no right to be on it, just hoot your horn as much as you can, and scowl at them, the pedestrian must stop and let you drive on.
Force your way out at a junction, or you will be waiting all day, again toot toot that horn while you push your way out.
In Manila Cianta area, watch out for motorcycles overtaking traffic by using the pavement; they will treat you, the pedestrian, as if you are not there.
A motor here, if its horn doesn't work, it meanss the motor is no use - it's broken.
