A scientifically tested theory that proves the following:

1) If you are driving a motor vehicle in the passing lane of a highway and are suddenly forced to slow down because of a slow moving vehicle, 9 times out of 10 the vehicle causing the slowing is a minivan.

2) If you are driving a motor vehicle in any lane of a highway or throughfare and another vehicle is tailgating you, there is a likely probability that the vehicle is a minivan and the driver is a MALE that is pissed off that he is driving a minivan.

The following observations conclude the following:

No matter what, Minivans will never aid your driving experience and will always make it worse in every instance.
Of course! A woman driving a minivan 30 miles an hour on the interstate. Do you need any further proof of minivan theory?
