Akala ko ba strict na ang LTO, MMDA, at PNP with regards to license plates?

I saw these two vehicles yesterday along Espana and Quezon Ave.

A black BMW 3 Series sedan with a front license plate that reads WCW648 and a rear license plate that reads S 1999.



A white Mitsubishi Lancer with a rear license plate that read XPF628 and a front license plate that reads MAYOR



What surprised me the most is that both vehicles were driven by female UST Medicine Students. Hay buhay...
