173's route is dangerous, its full of slopes, but drivers chiong
along the way. It seems that the 173 driver is at fault, cause it
seems that its doing what 173 drivers does best along Lor Kismis,
go onto the other half of Lor Kismis (there are no lane markings on
Lor Kismis and Toh Tuck Tce, very narrow roads, so one half is for
one direction, and the other is for the other direction)
