$12600 a year? Not even close.
I live in LA, my 2006 vehicle (which is paid for) gets 14 mpg in the city, I drive 3 miles each way for an average of 6 miles per day.
So... $370(6 month policy) * 2 = $740 for insurance that's full coverage, I just filled up my tank today at $42 that will last around 3 weeks, $728 a year for gasoline, an oil change $40 (I do it myself and use full synthetic oil)
My total yearly cost? Wow, a whole $1508 a year and yet I'm in the vehicle almost every day. My time is worth much, much more than trying to save that $1508 (I make around $70 an hour). That means my yearly transportation costs are around 1.5% of my after tax take home budget.
Before anyone points out tires/brakes/blah blah blah. Like I said I have a 2006 vehicle, I just rolled over 13,000 miles that's thirteen thousand miles, I didn't leave out a 0 or anything. It's going to be a few more years before I need to even think about those things.
Go ahead and pretend taking public transportation, adjusting yourself around their schedule, exposing yourself to sick people, etc is some great panacea. I'll keep driving thank you very much, and patting myself on the back for being such a genius that I chose to live within a couple of miles from work, and I still don't know what crazy rush hour traffic every one keeps talking about in LA.
What's next a story using creative calculus showing that stay at home mother's are worth $100k a year?....
