Pedestrians who think they have the authority on roads. Extra plus on those who give you the stink eye when you honk at them or, this is an extreme case I promise, when I *softly* bump them by my side mirror. Hey!! *&#(*@$%@ You don't see me driving on the pedestrian lane so move!!
People who makes use of the public transportation but does not have the decency to make use of the technology of continuous flowing water right in their homes. Seriously. It's so inconsiderate when smelly sons of bitches human beings take the public transport. It may seem like a bitchy move, but I will not hesitate showing my repulse (i.e covering of nose or breathing through my mouth)
I don't mind slow-walkers, it's easy to overtake them and hey, I sometimes walk slow too when I want to sightsee... but what I effing hate are those who walk in the middle parts (of pedestrian lanes, walkways, halls, etc) and have the indecency to suddenly stop. If I'm in a bad mood and I bump you or step on your shoe, the best you'll get from me is a grunt. Is it too much to ask for you to slowly merge to the side while you figure your shit out?
Broken tail-lights. I wish the Philippines would implement (or strictly implement) the broken tail-light policy. When I drive, I usually space out and sometimes taillights bring me back to consciousness and alert me that I need to step on the break pronto. Yes, my proneness to accident is above average. Anyway, you know what's more effing annoying? It's the rust-covered cars/jeeps/tricycles that usually have broken lights and jeez, if you ever bump one... your car will absorb more physical damage than them.
Okay, I just noticed now that my pet peeves usually involve modes of transportation. Hmm.
