What I've seen a lot of are cars that stop short behind another car,
and then creep forward to a reasonable distance after they've stopped.
the car following, if it's a stickshift, may choose not to do the same
to save wear and tear on the clutch. Happened to me quite a bit; I
will stop a reasonable distance (just enough that I can swing onto the
shoulder if I have to) behind another car, and then he'll creep forward
10-15 feet or more, leaving a huge gap between us. Not sure why people
do this, unless they're just completely unable to modulate their
braking.

I do that often when I've got somebody tailgating me. As I stop, I watch my
mirror to make sure the moron behind me stops. After we're both stopped,
then I close the gap. -Dave
