Unclear if NEA PSI index is truly lagging as it is a 3 hour average.
PSI conditions have passed the 400 mark which is deemed hazardous and yet, as of 2pm we can see that it is only 355.
We have always pride ourselves in economic efficiency but when it comes to such crisis, even Malaysia is faster than us in reacting.
