I've come to realize something. For as long as I know, people have called a car wreck an accident.
An accident is an incidental and unplanned event that could have been prevented had circumstances leading up to the accident been recognized, and acted upon, prior to its occurrence. –wikipedia (The definitive source on everything).
I believe what is most often referred to as an accident isn't. True, I don't think someone meant to have a wreck. But, I don't consider a car wreck an accident because I put a lot of stock on the phrase above, "could have been prevented had circumstances leading up to the accident been recognized."
Since an accident can be avoided, I call them wrecks and blame it on inattentive driving. While driving, it is easy to pay attention to other things going on around: billboards, neighboring drivers and passengers (some are quite entertaining), road construction, favorite song on the radio, our phones and even others in our car.
Actually, a lot of accidents (mistakes) in life can be blamed on inattentiveness. Budgeting, planning, editing, working and relationships all suffer with inattentiveness. The temptation to multitask is huge with so much vying for our attention. A recent Forbes article actually points to the negative effects and decrease of productivity associated with multitasking. Each of us has one incredible brain that is best suited for focusing on a single task.
