Composition of Jam @ Custom

The traffic jam @ our custom (with reference to Woodlands one), the gate-way between S'pore & M'sia can be really bad. Many times, the faster way to cross over is by foot, literally.
I'm not complaining this time.
I shall try to provide another perspective.

If an attempt were to be made of the "composition" of the jam, we find :

- Big trucks.
These are the main "obstructors". They literally block everyone in their path. Besides, it is understandable they will take longer than usual to clear the custom. They are essentially part of the trading teams between the two countries. They can be 'annoying' and 'noisy' (most of the time).

- Buses.
Their sheer size is equally 'threatening' as the above. They are mostly factory buses fetching workers back home to M'sia.

- Cars.
There are many. Are the drivers of these cars, necessarily holiday makers of some kind? Haha.. not necessary ba. Many of these drivers travel to-and-fro very regularly. They either have families/friends on both sides or working here while staying at M'sia (very unlikely to be staying here and working in M'sia), making travelling between the two countries (almost) a daily affair.

- Motor-Cycles.
I find this the most amazing. They appear in thousands. No joke. The sound/noise they produce while in the queue is unmistakeable. The bikes are so packed together and they move by inches. The riders will not be able to stretch their legs too much, laterally and have to constantly watch out for the hot engine exhaust very near them. If we look closer, almost all (if not all) of the riders are pretty expressionless. They can also look real tired. This is unlike drivers and passengers in cars who are almost always observed to be engaging in small talks.
Heh.. do remember the exhaust-fumes the riders are breathing in at the same time. Okay, some do have a towel wrapped around their nose and mouth. That is an attempt to protect themselves, but does it help? Many riders are also not wearing safety helmet (yes, even while they are in the queue on the S'pore side).
Anyway, these riders are mostly M'sia citizens.
I don't think anyone will find such a jam-experience of the bike, in any sense enjoyable. Yet why are so many riders making such journeys everyday?
They work here, but stay and spend there. The currency conversion rate makes it a economically viable option.

I must add on. Besides the riders, there are also many more aunties and uncles working here and need to make daily to-and-fro journeys between the two countries. They usually travel by company (big) buses. The bike riders only make it more observable for me.

Actually, I admire these M'sians quite a lot.
(1) For their future and family, they are willing to make the sacrifice. Maybe they don't even view it as a sacrifice at all. But just imagine, returning home just after mid-night and coming back to S'pore the next day (technically speaking, it's the same day) in the morning to work again. They hardly have time for their families and friends.
(2) I sense their fighting spirit. Not many S'poreans can take that kind of life, I think.

Wa.. don't dare to say my life is tough ah.
