If you all have noticed, transportation after midnite is always
very expensive in Spore. It cost average $20+ so one way to save
money is try to leave for home before last bus/MRT service or
restrict yourself to once or twice such luxuries.
If you find yourself almost everyday need that, it maybe more
worthwhile to invest in a car cuz it is cheaper (debatable of cuz).
For some who strike a balance, they opt for a motorbike (downside
is tendency of accident can be higher) but of cuz for those who
ride safely, it is win-win for them.
Sorry for not revealing how much I spent cuz I only spent on
electricity and water as I nua at home watch TV
