Years ago, we conducted an experiment.

My brother & cousins would weave in & out of traffic (ala PUV jeep/taxi driver) arangkada as fast as they could, ayaw magpasingit etc., yung typical scumbag Pinoy driver style of driving, you get the idea... while ako naman yung base/reference vehicle. Sumasabay lang sa speed/flow ng traffic, sumesenyas properly, nagbibigay etc.

You know what? The time diff between our arrival at our destination was mga 15 min lang, more or less.

Some wise ass might say those 15min would really matter, but that's because you probably left the house a little late in the first place anyway, so partly kasalanan mo rin kaya ka may problem. Then bwisit ka sa mundo mag drive expecting the world ought to give way for you. The world doesn't revolve around you and your needs (sino ka???)
