I don't know if it's just me, but there seem to be more and more stickers on the back of truck trailers saying "Our drivers make $0.XX / mile!" Never used to see that. (Of course, possibly just a cover for the wait-to-load-for-free gigs)

Also saw a billboard the other day for some trucking company advertising "Honey, I'm home weekends!"

The airline industry might take a hint from these guys.
