For over a generation already, most of the public drivers had their training either from driving a truck, a tricycle, or a jeep, without proper guidance, and without working signal lights. Plus for almost a decade, the inner lanes of our streets are virtually dangerous to use because it is occupied by parked vehicles, that's why cars nowadays travel on the center lane either by (no choice) or by instinct (due to consistently no choice in other streets). Eventually, other more disciplined drivers are forced to follow the majority, and either do it out of no choice, or eventually developed such bad habits unconsciously.
Yan ang problema ng pinoy dito sa pinas. Dito lang yan, kasi pag nag drive ka naman sa labas, nagiging conscious na naman tayo about what is the right and wrong way to drive.
