Not just in EDSA, in any clogged major road, sobrang dami yung mahilig umovertake ng alanganin especially in moderate (~40 kph) speeds. Pag slow traffic, singitan talaga yan and hindi maiiwasan pag nagbigay ka ng space. Hindi ako sumisingit pero I keep a close distance (just far enough to avoid hitting in case of sudden braking) para hindi rin masingitan.

Kapag naovertakean naman, it's proper motoring etiquette to let them pass you. Hindi yung mabagal ka tas pag inunahan ka na bibilis ka rin. Papansin na, bastos pa. If you really want to speed up, then at least let the passing car complete his maneuver and then overtake when you have a clear chance.
