I haven't really done a serious cost comparison between owning a car and using public transport. I've always thought using a public transport comes out to be cheaper than owning a car and is a lot safer and you get to do other things while you commute. Paying the insurance and regular maintenance costs add to your overall expenditure.
If you live closer to work, friends and family, maybe you don't really need a car. However if you have to travel longer distance regularly, then this may not be a right option for you. Personally, I can still go on without a car. Any thoughts?
