How to do it

Gary,

You've suggested the 3 stripes idea a few times, and I imagine it's a good way to measure 3 seconds at highway speed. I'd state it a little differently -- stay just far enough back that you can see the truck's mirrors sometimes but not all the time (which should still leave the back of your car in the trucker's view), or just count off 2 to 3 seconds.

I think it's a generational thing; your generation may have been taught to count lines, but mine was taught to count seconds. I can't seem to count lines without focusing on them too much and removing too much attention from the road, but I can count seconds without diverting my attention.
