Whats up with motorcycle drivers driving in the center lines or lane lines these days?

Ang dami ng motorcycle riders ngayon na sobrang reckless at walang pakialam sa kaligtasan ng iba. Madalas silang dumadaan sa gitna ng lane lines or center lines, parang sila lang ang may karapatan sa kalsada. Almost everyday I see these people driving within the center, they often get mad when you beep at them or you may even hear them curse or shout at you too lol. Wala na bang gagawin tong mga enforcers about these? At ang nakakainis pa, sila pa 'yung galit kapag naharangan mo sila o hindi ka nagbigay daan. Sila pa ang malakas loob, tapos sila 'yung nagagalit kapag may nakakasalubong na hindi sumunod sa kanila. Tapos, kapag may aksidente o disgrasya, sila pa 'yung unang magdadramang biktima. Parang hindi nila naiisip kung gaano ka-dangerous 'yung ginagawa nila, tapos sila pa 'yung unang magmamagaling. How did this trend even start? Bakit biglang dumami ang mga kamote drivers, at yung iba naman naging premium kamote drivers? Sobrang bilis ng pagdami nila, It's like the more reckless they get, the more they feel entitled to the road. Oh and btw these photos are taken at Ortigas Ext Ave. Papuntang antipolo po, these instances are not just happening here but everywhere else too!
