According to a couple of LTO folks that I know, all motor vehicies, whether PUV or PV, would be required to install RFIDs on their winshields starting October 1. Sabi din nila, it should be placed where it would be "most visible" on the windshield. Cost is 300-350 pesos. Pero since hindi naman daw lahat makakabile agad, may grace period sila bago manghuli.
EDSA traveler here. Pardon my negativity but I can just imagine MMDA traffic personnel having a field day apprehending vehicles that do not have RFID attached. Good intentions from LTO perhaps but another possible source of kotong.
