They may only need it once a week or a month. What to do with the car for the rest of the days? Isn't rental car better?
Such half cooked ideas would only give rise to more problems than solving thems

The average white collar worker in SG who drives to office is only on the road for 1 hour a day, so he doesn't really add to the congestion. His car is parked at his workplace for 8-9 hours.  Why penalise PMEs like him? Have a separate category of COEs for PHVs and taxis who are contributing to traffic congestion for almost the entire day.
