I have been seeing these LTA bikes parked under the flyover in various locations since 2-3 years ago. They are always there even on weekends.
Here are some photos showing LTA enforcement motorcycles parked at two places: Mandai and Braddell Road.
Are they eating snakes or working? Because I ever saw them lying down on some recliner chair under the Braddell Flyover when I was driving past slowly.
If they are eating snakes, then it's really a waste of taxpayers' money.
