Napansin ko lang yang mga tinted plate covers after reading this thread and true enough, yesterday while driving I saw an innova with tinted plate covers.
Nung papalapit kami sa kanya, I read his plate as *VM, di masyadong kita yung taas because of reflected light and shadows. When we got nearer, *DM pala.
Could this also be true for non-tinted acrylic plate covers? I don't know but I intend to find out. Observe pa ko ng ibang vehicles... acrylic kasi yung sa min e.
