I guess we cannot deny that buses can reach speeds that are
faster than so-called permissible limits. But bearing in mind that
speedometers in Singapore, fitted to every vehicle except for
Police/Fire Department vehicles and except for those that are
tempered with, shows only 95 percent of the true speed. Hence, at
70km/h, the true speed is 66.5km/h, which is still, and definitely,
over the speed limit.
I have only saw notices, the most in Yishun Interchange, reminding
BCs not to dirty the driving cab and keep the bus clean, but never,
notices saying 'Do not temper the speed limiter', and I would too
wonder, who would do that? Do you temper the speed limiter just to
reach the destination faster, maybe for Malaysia, but not here, in
small Singapore, where everything is just a stone's throw
away.
We do have to look out for buses with tempered speed limiters, even
if you are not going to complain...
