So let's say I get approximately 4 miles more per gallon driving 60mph instead of 70mph on the freeway. Right now, my average fuel economy runs about 28mpg, so let's assume that if I slowed down it would be 32mpg. At cost of $3.75 per gallon we can calculate my per mile fuel cost for each speed:
cost per gallon/miles per gallon = $.134/mile (at 70) and $.117/mile (at 60).
Now lets say I take a long trip of 420 miles. I use this distance because it's evenly divisible by 70 and 60. Now let's compare our two scenarios
At 70mph:
Trip time = Trip distance/Trip speed = 420miles/70mph = 6 hours.
Cost = Trip distance*cost per mile = 420miles*$.134/mile = $56.28
At 60mph:
Trip time = 420miles/60mph = 7 hours
Cost = 420miles*$.117/mile = $49.14
So each hour extra I spend driving I save about $7. Thus, I am essentially paying myself minimum wage to drive. That's ridiculous. I charge $80 per hour for tutoring and often choose not to tutor because I don't want to spend the time doing it. Even if I only net $60 per hour (which is way low considering I do most of my tutoring at school) for tutoring considering wear and tear on my vehicle, fuel costs, and travel time, then 1 hour of tutoring would allow me to drive faster for about (60/7)*420miles which is roughly 3500miles, which is more than I drive total in 2 months.
Thus, 1 extra tutoring every two months will allow me to drive faster on the freeway saving me a total of between 7 and 8 hours time depending on the time it takes to drive to and from tutoring for the same total net monetary cost. That's an entire work day.
This is why I still drive fast on the freeway.

Long live the ever-growing consumption mentality that drives America, and enslaves us to foreign entities!
I'm all for conservation, and I'll even pay more for it. The issue here is time. I can make money easier than I can make time, so when I'm short on time, I drive fast. If I've got the time, I slow down.
