Over the past week I have conducted extensive observations over thousands of miles of open road tests (I don’t send text messages while driving like you do). Based on this study, I can tell you that people tend to drive five to fifteen miles faster than the posted speed limit.
Most of the tests were conducted on two-lane interstate highways up and down the east coast including I-4, I-75, I-77, I-81, I-84 and I-95.
Speed limits were anywhere from 50 to 70 MPH, tending towards the high end south of the Mason-Dixon line where NASCAR reigns.
Almost nobody drives below sixty. Next time you’re on a highway pay attention to how few cars drive slower than that. There are two reasons for this. The first is that we are notoriously bad at math.
Because there are sixty minutes in an hour, most of us can figure out that when we drive sixty miles per hour we are going one mile a minute, and can estimate how long it will take to get somewhere. Having to calculate this for any other speed, in our heads, while driving, causes us to break into a sweat. The only thing we know for sure is that anything faster than 60 MPH is at least a mile a minute.
That makes it a good deal. We’re getting wherever we are going just a little bit quicker. Anything slower than sixty makes us worry that we’ll end up getting there late. We just don’t know how late. And let’s face it: we left a little later than we should have.
The other reason that we drive so fast is that we love our freedom. We look at speed limits as suggestions. Whatever the limit is, you can be sure that only a small percentage of cars on the road are moving at or below that speed. Especially when there are no cops around.
That’s the American way.
We were founded, remember, by people looking for a place where they could escape religious persecution. This way they could be free to follow their own beliefs, which often included the persecution of those who didn’t follow their beliefs.
Hundreds of years later this spirit manifests itself on our two-lane interstates, where the only thing more annoying than the driver who comes up fast in the left lane, only to lose the nerve to pass me when he pulls alongside my left rear bumper forcing me to slam on my brakes as I come up on the slow-moving truck in front of me, is the driver who decides at the last second that he doesn’t want me to go ahead of him and pulls into the left lane in front of me, thereby imposing his maximum speed on me and limiting my freedom to move at my own pace.
Then, when I tailgate him, he decides to teach me a lesson about obeying the speed limit, and slows down some more.
I hate thy holier-than-thou attitude.
The same weakness with math leads us to think that a gallon of gas that costs $2.99 and nine-tenths only costs $2.99. We round that nine-tenths of a penny down. But when we buy ten gallons of gas we don’t save ten cents; we save a penny.
I have no idea why the price of gas is calculated to a tenth of a penny, other than that it is one more way we deceive ourselves about the real cost of automobiles in our lives.
On I-75 in Florida I passed a car with a bumper sticker that read:
I’ll keep my guns, my freedom, and my money – you can keep the “Change”!
The guy with the bumper sticker probably hasn’t finished paying for his car yet. He has to pay for car insurance, and his registration, and his driver’s license. He’s probably running a hefty credit card balance and might also have a mortgage.
The website fueleconomy.gov reports that passenger cars are most fuel-efficient at 60 MPH. Every five miles you drive over 60 MPH is like paying an additional twenty-four cents per gallon of gas.
The quickest, most pain-free way to reduce our dependence on foreign oil is to slow down.
But that’s not the American way.
That guy really doesn’t have the freedom he thinks he has. And he really isn’t holding on to his money. Not at the speed he was going.
Just in case the guy already knew that he doesn’t have two of the things he values most, but still had the third thing, I did not tailgate him.
The stretch of I-4 around Orlando, Florida is loaded with theme parks, but the one that caught my eye was called Holy Land Experience.
Florida is a strange place.
Most of the roads are very straight and flat, something that a New Englander has a hard time comprehending. This may be to make things easier for all of the old people who live there, or for the minivans full of families heading to and from the theme parks. Straight roads make it easy for drivers to break up fights between siblings in the third row without slowing down.
There are a lot of churches in Florida. Most of the churches have names like First Unity Church. I didn’t see many Second or Third churches, though I did see a Mary, Queen of the Universe Church (also on I-4). This has nothing to do with the extreme flatness of Florida, or with the Holy Land Experience theme park, which looked like it belonged in Las Vegas.
I confess that my first thought on seeing the Holy Land Experience sign (besides ‘wow, that looks like a casino!’) was yes, but whose Holy Land? Which seems to make the Holy Land Experience theme park the real deal.
But then I became distracted thinking about what went on inside the place. Were there rides? Was there a water park (perhaps it was called Noah’s Water Park?) Was there a wave pool that simulated Moses parting the Red Sea?
Then two of my kids started fighting over some toy in the third row of the minivan, and I threatened that I would take it and throw it out the window. This got me thinking about the Holy Land Experience again, and whether Jews and Christians and Moslems might stop fighting over it if they were presented with a choice like the one Solomon gave the two mothers in the bible story, when he threatened to cut the baby each one claimed in half to satisfy both of them.
Then I had to pass another truck.
