Fuel Mileage Experiment, Week 2

Week two of the fuel mileage experiment has ended. Here are the results of week two:
Mileage: 273.1 miles
Gasoline Used: 9.862 G
Miles per gallon: 27.69

So this week, with the same assumed $4/gallon, it cost me $39.45 to drive those 273.1 miles, for a cost of 14.44 cents per mile. As expected, this is higher, but only slightly higher, than the 13.77 cents per mile cost of driving at the speed limit. Also, as expected, I'm getting slightly lower fuel mileage, 27.69 mpg compared to 29.05, a difference of 1.36 mpg.

Assuming my average times to work are accurate, here are the raw costs of driving back and forth to work for one week, and going nowhere else:
Total miles, one way: 23.3
Total number of one-way trips: 10
Total miles per week: 233
Slow driving time, per trip: 25 minutes
Slow driving time, per week: 250 minutes
Fast driving time, per trip: 22 minutes
Fast driving time, per week: 220 minutes
Time savings for fast driving: 30 minutes/week
Slow driving fuel costs, per week: $32.08
Fast driving fuel costs, per week: $33.66
Cost savings for slow driving: $1.58
Per hour compensation for slow driving: $3.16

Wow. $3.16 per hour. That is how much I am compensated for driving slowly.

Now, I'm sure some of you are thinking, "Yes, but if you drive the speed limit, you won't get a speeding ticket, whereas if you are speeding you run the risk of getting a speeding ticket." True. That will throw off the calculations.

For fun, let's figure out how often I would have to get a speeding ticket in order to compensate myself at minimum wage for driving the speed limit.
Minimum wage: $6.55
Less current slow-driving compensation: $3.39
Per-week difference: $1.70
Assumed cost of a speeding ticket: $100

Using these numbers, if you got a $100 speeding ticket more frequently than once every 59 weeks, it would make up the difference. That's not quite one speeding ticket per year.

Of course, you don't have to stay within the speed limit to avoid getting a ticket; you just have to stay under the "real" speed limit, whatever that is. For the record, I've never had a speeding ticket yet, knock on wood.
