Hi,
I printed out a sign this morning:
45.5 mpg
Overall
EcoModder.com
(which is my average for the last 6 tankfuls)...and after cutting it out, I taped it to the inside lower left corner of the hatch window. It sits in a blind spot (rear seat headrest), so I'm not endangering myself.
I tried to notice if anybody reacted to it on my commute this morning; but nobody gave any indications...
