Cars are money pits. So in the world of personal finance avoiding them is often worth some consideration. When you include insurance, gas, oil changes, other maintenance and depreciation you can spend around $4000/year with out trying hard. So that is why my second car is the bus.
You see we don’t need a second vehicle all that often, perhaps a couple times of month. So rather than keep a second car for those odd times I invest $18 in a sheet of 10 bus tickets and keep them in my wallet (they don’t expire ever). That way I’ve never looking for change to take the bus (also it’s cheaper than the $2.25 per fare). So at the upper limit I spend $172 per year on bus fare, which compared to $4000 is steal of a deal.
Then there is the time factor. Yes it takes me longer to get to and from work by an hour in total, but I also get some extra reading done on those days. So all in all I consider the whole thing a small price to pay to save around $3800/year. On a hourly basis per year that works to $158/hour in savings which is certainly a hell of a lot more than I make at my job.
So yes you can call taking the bus good for the environment in lowering greenhouse gas emissions, but really I’m doing it to save a small fortune in costs. So don’t always think that reducing your carbon footprint makes you spend more, often it is about fattening your wallet.
