So sorry to hear Cathylmg, these days i don't pay them if its really not my fault. We did encounter a few times when they checked out passport, etc but didn't ask for anything at all. Just waved us to pass.
As for blaring cars, seems there was some car show event nearby as lots were doing car displays with loudspeakers and amazing car mods and lights. I saw many and not only one ethnic group. Seems to be a pretty major event.
Stopped by just now as there was a SG car in need of help. It was a very rainy day, even though i turned on my hazard lights, another car behind me blared away even though he was way behind and i was in the extreme left lane. Turned out that the driver was trying to find where was the 2nd link as he tried the new highway and couldn't get through. I explained to him that it wasn't open yet but he can drive down, get to the traffic light where he can see Jusco, go straight down the highway which says Tuas. I told him that its very straightforward and offered to help if he needed but he said it was fine. It was a bit strange though as there was like 5 of them standing in the rain and no one knew where to go.
The gent and his buddies (all SG Indians) were all very happy and i wished them on their way. Shortly after, it rained like nobodys business, i hope they got back safely.
