I don't think it is a waste of time. In fact, I think it is a good start. The exercise cannot duplicate the actual situation (as mention by sammy888) but at least it give the agencies the practise and the chance to iron out issues arise from the execise.
If you watch the TV or read the paper, you will notices that people are rushing to board the bus and a lady was injured in the process. People complaining the inconvience cause to them because they do not know that there will be such an exercise (this was announce in TV and newspaper for the past weeks?).
From this exercise, I notices that
1. Majority of people in Singapore are "selfish". Rushing to board the bus without consideration for others is just one example. This can be seen everyday too.
2. People in Singapore complained that it inconvient them but never thought of the 2000+ people willing to sacrifise their Sunday to take part in this exercise.
3. People in Singapore complained when the exercise affect their life. When it actually happen, they will complain that the agencies never prepare for it.
4. People in Singapore are ignorance. Expect the government to take care of everythings.
In fact, it is never safe living in this world. Even staying at home can be dangerous. You never know when a plane might fall off from the sky and slammed into your home. You never know when the building will collapse. You never know when you will choke while on your food. Yes, these are extreme example but that is what the meaning of the word accident. We should be thankful when we wake up every morning because we have live though the night

..
I would like to say "Well Done" to those take part in this first exercise although there are room for improvement.
Hopefully future exercises will become more and more realistic.
