ako naman i park facing the wall, sometimes even if the parking bldg (or whatever) doesnt require it. kasi ang tendency ng mga tao, is when they park backwards..they will park all the way. meaning, hihintaytin nila tumama yung rear wheel nila and then stop backing up. ung bang pasok na pasok sila sa parking slot. ang sa akin lang is safety na rin..so i think mas ok na park facing the wall, kasi you tend not to park all the way thru, kasi baka tumama yung engine brace mo or something else, so yung backside of your car is well-seen with others. para alam ng mga ibang tao kung meron pang slots available or not.
