a slacdrafter is the slow and curious driver. they are the ones who drive right on your rear bumper. but will never pass.
we've all seen this person, the "slacdrafter" usually driving a 4 cylinder, that ranges from lime green to beige. they are the ones who drive right on your butt. but will never pass. Instead they hope that you will continue speeding in their direction.even when you change lanes, they change with you, or slow down, because they know you will get back in the fast lane sooner than later. and hopefully, if a police officer is anywhere near, they will stop you, while the drafter searches for his next speeder.
