MW, think u mixed up liao.
Every car scrapped will allow a new car back on the road. This will not add more cars to the road since one for one replacement.
Garmen allows 0.5% vehicle growth, this is over and above the scrapped cars' COE recycling back in to the system.
Yes, COE system was messed up whren Raymond Lim was around, they used some forecast method to anticipate number of cars scrapped and this method is obviously beh zun hence they released more COEs than suppose to. Hence car population growth was more than the 3% they allowed during that time and hence the congestion we are in today.
They realise the mess we are in some time before the erection and now how many COE being recycled is based on actual number of cars scrapped instead of by forecasting. At the same time they reduced the allowable car population growth from 3% to1,5% and then to 0.5% soon. Hence the COE price is what it is today.
Above is my understanding of the story, I stand corrected though...old man bad memory.
Simi COE price high due to economy good? Totally rubbish, COE price is no where near what it is today before Lehman in 08. COE price is high cause we are paying the price of the above mistake.
