The first time I've seen this, not sure whether it's unusual
though.
Today, at around 4pm onwards, at BNL at the turn between Berth 7
(174, etc) & Berth 8 (179, 180, etc), 2 SBST green men were
standing there. Whenever a bus came, they would raise a speed gun
radar thing and aim at the bus. It was very obvious. It led to all
the buses driving very slowly when approaching that turn!
All the buses coasted at about 5km/h when at the
turn...
the SBST
guys even aimed at an SMRT WA Scania which ignored it and sped
through the turn...
There was
also one of the pro 179 drivers (the 19min record guy) on 242
x-over. When he left the 242 berth, he accelerated very fast, but
once he saw the guys raising the gun, he quickly braked and coasted
slowly past the men.
I think it's useless... If they really wanted to catch drivers
speeding in the interchange, they shouldn't make it too obvious...
Moreover, they seemed too friendly... When the buses drove past
them, most of the drivers smiled and waved at the green men...
