I spent around $4000 last year driving to work, and that's just gas and insurance. Oil changes every couple of months, tires, minor repairs here and there, etc. It's not worth it to me anymore, but I'm not fit enough yet to commute by bike 62 miles every day.
And I'd have to get up so early and get home so late that I'd only get something like 5 hours of sleep every night.
Plus there's the fact that I would be roadkill within the first ten miles on the first day. lol
