Traffic School - Predictability
Posted by: Jeff Larson on May 17, 2007 at 10:11AM EST


When you’re driving, you observe the overall flow of traffic. Traffic moves in a fluid manner, not dissimilar from the movement of a river or stream. Not everyone is moving at the same pace, but there’s a general flow that is predictable and observable. When a vehicle enters this flow by bouncing from lane to lane and changing speeds, it interrupts the flow. It creates an unpredictable commotion. It’s in this commotion, this disruption, that there is a higher risk of collisions and injury.

Predictability may not be something you ascribe to in daily life. It’s not considered romantic to be predictable, but it’s a very important in being a good driver.

You’ve seen the driver who is all over the road weaving between lanes, tailgating, and speeding up or slowing down. He’s always looking for the fastest lane, impatient to get there, wherever that may be, as fast as possible.

This kind of driving behavior causes accidents. When someone is driving unpredictably at varying speeds and quickly changing lanes in an unsafe manner, it makes it much more likely that other people will make a wrong decision. It’s also much more likely that other drivers will be unaware of his presence. Often it’s the case that this kind of erratic behavior will result in a collision that doesn’t even involve the driver who was acting erratically.

The ironic thing is that this erratic (bad) driver likely thinks he’s a good driver. That’s why he’s driving like he is. It’s this unfounded confidence in his own ability that convinces him that he can drive in a far riskier manner without consequence. It disregards the needs of other drivers for predictable and consistent behavior on the part of other drivers. It’s this false skill that puts the rest of us in danger. We have no way of knowing where he is going next, if we even know he’s there in the first place. This unpredictability is a major issue in collisions.

The truth is the actual amount of time saved by a driver weaving in an out of traffic is quite small. Admittedly it is a little faster, but only a little. Let’s list the downside:

  • Increased likelihood of crash – in the event of a crash…
    • Cost of repair
    • Lost time of due to repair
    • Potential injury
    • Lost time due to injury
    • Cost of injury treatment
    • Increased auto insurance rates (for everyone)
  • It’s rude.
  • Wastes gas - Excessive accelerating and decelerating burns much more fuel.
  • Increases stress
  • Increases road rage
  • Increased wear and tear on vehicle

The fact is, the more chances you take on the road, the more you change lanes, weaving in and out of traffic, the greater likelihood that you will make a bad choice. Even if you have better reaction time and better reflexes than the rest of us, the fact that you are driving in such a risky manner means that you are more likely to be involved in, or cause an accident.

While the sermon is appreciated, reverend, I think you're not gonna convert this group of cannibals to the faith.

Bad drivers are like impossible people, they are literally incapable of realizing they are bad drivers...and thus you can't change their behavior through reasoned argument, no matter how good or convincing that argument is.

http://www.wikihow.com/Deal-With-Impossible-People

The only way to change that behavior is to FORCE a change. Either through increased traffic law enforcement (which has a questionable efficacy at best) or through technology (speed governors, lane monitors, etc) or through highway design (reduce capacity to force traffic jams that lower speeds)

Unfortunately we live in a country where the most sacred and cherished right is to act like a total idiot. So any of the above solutions is unlikely to be implemented.

Brad,


I don't disagree with anything you say. Better enforcement, better laws, better road design and better technology would help to make people drive better. But I also know that there is no single magic bullet to improving the quality of drivers in Massachusetts. None of those things alone would solve the problem.


I don’t expect that bad drivers will read, or care about these windy, preachy Traffic School blogs. Bad drivers are bad drivers. Period. They think they’re good drivers, but they’re not. I’m hoping to get good drivers to become better still by thinking about how they react to daily conditions and improving their awareness and subtle driving skills.


I’m a fairly conservative driver, but I’m not perfect, I occasionally make bad decisions, or lack awareness in some situations I think most people are that way. Most people are good drivers. But everyone can improve. So my thought is to get good drivers to improve, to reduce the number of bad decisions we make.

Well, for what it's worth...I freely admit that I'm a terrible driver. My wife will admit that I'm a terrible driver, too. :-)

Fortunately, I take the T to work...so at least I'm not out there terrorizing the roads TOO much.
