I’ve made a few posts about my gas consumption, i.e. I washed my car the other day, oh boy! and Gas Mileage (a comparison between my 1990 Jeep Cherokee and my 2006 Ford Escape), topics that everyone is concerned with, but posts that I imagine few find interesting. Nevertheless, here is an interesting(?) update.
Fig 1. Red dots show data from the previous examination, blue dots show recently updated data. The solid green lines are fits to the two data sets. Significant deviations are annotated, curiously, I’ve failed to annotate the three weeks I spent in Europe and Africa.
It would seem that I have held fast to my desire to reduce unnecessary driving. I’ve reasoned that I need an average minimum of 16 miles per day, the trend in the old data was 32 miles per day. The new trend suggests that I am now averaging 23 miles per day. My vehicle gets about 23 miles per gallon, so I spend an average of $2.72 a day on gas (see Fig 2). That’s nearly $1000 a year, or an large LCD HDTV.
Fig 2. Red dots show data from the previous examination, blue dots show recently updated data. The solid green line is a periodic sine wave with a period of one year, the mean price of gas is found to be $2.72 per gallon.
As an alternative, I’ve been considering taking the bus to school, it cuts out a significant portion of my necessary driving, about 12 miles per day, but adds an hour to my traditionally 15 minute one-way commute. The bus pass is $50 a month, so $600 a year. Total personal savings, $400 a year.
But now consider the additional time: two hours total for every day I go to school, if I have to go four days of the week, and there are ten weeks in a quarter, and three quarters a year, I will have to justify at minimum of 240 hours per year lost to commute. In wages, during my commute, I am making myself $1.67 per hour, versus ~$16-18 per hour of real work. But then the environment, higher gas prices, and the pleasure that the solitary hour bus ride where I need not think about any thing in particular can provide.
Decisions are the worst.
