My Dad will get in his car and drive across a parking lot rather than walk it, even though it takes longer. He'll sometimes wait for several minutes for someone to leave in their car rather than face a 45 second walk across a parking lot. He acknowledges the irrationality of this behaviour when I tease him about it, but he won't change.

On the other hand, he keeps fit, enjoys walking recreationally and happily walks for miles when hiking, golfing, or fishing. But he'll drive his car as close as possible to the start of the trail first.
