I'd love to see something happen to make all the smoke-belching vehicles, of every sort, simply disappear. But we all know that ain't gonna happen. It's a good idea, but with no plans in place to help it happen. Do the powers that be actually think they can force jeepney owners to scrap their old vehicles and buy new ones? Or replace the engines? Most jeepney owners don't have enough money saved to buy new tires let alone a new engine, or even less, a new jeepney. So, what will happen? A few people will be made an example of to show the bigger powers that the locals are "doing something" about pollution, and then the whole program will fall apart just in time for the next Presidential election. The new guy/gal will promise everyone a new plan, "a jeepney in every pot!" sorta thing, and that, too, will fall apart.
I love the PH, and I love it's people, for the most part. But the reality is that they have a completely different outlook on what works for them and what doesn't. As long as a jeepney owner/drive can make enough pisos to buy some fish and rice for his ever-burgeoning family, he's good to go. Rules be damned! What are they going to do when 90% of the jeepney owners fail to comply? Shut down public transportation? The wailing would be so loud and with such fervor the powers sitting up in the winter capital in Baguio would be able to hear them. The People Power Revolution would pale in comparison to the outcry from the poor, downtrodden workers and students that still have to find a way to their meager jobs and classes.
Yeah, good idea, but not well-thought out. I don't see it happening in three, or even thirty years. JMHO of course. YMMV
