That sign is sweet.

How cool! I always wondered if something like that could be done...

I would put something like: current mpg to date ... 68.9 MPG. Then update it every time you add a tank to cleanmpg. There's also:

Please drive responsibly
if you can read this you're too close
refrain from tailgating

and of course:
get off my bumper jackass
your momma is so fat she looses 2mpg everywhere she goes
breathe, you're not late, relax
eat my......unpolluted air
my @$$^*#$ makes more gas than this car
mmmm.... fuelsavings
gas at $3.49 a gallon, are you driving the right car?
