TP not stupid
they always set camera along road that has changes on speed
limit
e.g.
along toa payoh stretch
the speed limit changes from 90 down to 80, so if you cruse along
100, good luck to you la, because they will not spend / waste time,
this kind sure can catch.
also along 50 km/h road
those g plate & y plate sure kina want
their speed limt is now 70, but the road is only 50
the smart TP plan well to catch
