I'm quite disappointed most of the new taxis are still using
diesel, not CNG. Hope the govt provide greater support towards a
cleaner air and build more refilling stations islandwide to
encourage car users and taxis to switch to CNG. Its common to have
a CNG refilling bay at majority of petrol kiosks such as Australia
and even Malaysia!
off-topic: What about CNG motorbikes, lorries, vans, etc etc
too?
