Those which go past several expressway exits before exiting
one.
The ones which enter and exit at the very next exit are not counted
(e.g 8,26, 31, 45 etc are not counted)
For those which travel for a significant distance, those I can
recall are 30, 97, 857, 190, 197,198, 154, 52, 59, 985, 168 (this
service travels a hell lot of distance on SLE/TPE
), 23, 36, 48
Any more?
