I think the reason why traffic is so bad can't be solely blamed on PUB/PUJ, taxis, etc. We ourselves can/should be blamed for it as well for not giving way. The more we don't give way, the more the flow of traffic will be jammed. I myself am guilty for not giving way sometimes, but I guess it already became instilled in our nature as drivers in Metro Manila. Constantly battling it out with public utility vehicles, trying not to be cut off by aggressive drivers. Though PUV's are also a big factor, its not the main reason. Thats just what i think, at least.
