Haven't we established that we're going to call safe distances "following" now, because it's not close enough to be "drafting"? Kind of a way to differentiate between safe and unsafe. CFD results in another thread showed a significant improvement in MPG at two or even three seconds back at highway speed. This is not drafting- it's taking advantage of someone else's wake, safely. Following.

Let's use these terms separately instead of regarding all drafting and following as "OMG drafting dangerous suicide!!1!!!!11!" There is a safe way to do it and still reap the benefits- using the 2 second rule- and we call it "following".

That said, if truck drivers have a problem with you following too closely they will let you know by changing lanes or, if you don't get the message, slowing down drastically. Look out for these signs if you're following.
