I was kinda thinking this too. I used to think that it would be funny to put a radiation sign on the back of the Prius but the joke might wear off in the even that I wreck and the fire department takes the sign seriously. Probably best to keep away from things that could draw the wrong kind of attention in the wrong circumstances.
In LA I would play the sympathy card instead. Something like "Can't drive faster, only have 3 working cylinders". If/when the cop pulls me over, I would tell them the truth and hope for mercy (ha ha ha ha!!!!).
Better yet (for me): "Caution: The driver is only working on 3-cylinders!"
I too get nervous about people riding my arse, but they just later pass and all is forgotten (that is until I coast up to them at the next light )
Fuel Economy Experiment In Progress, Please stay back!
excellent idea! I've been thinking about something like that since I've slowed my speeds down on the highway. I was thinking something like "save gas, slow down", but your's is much better. Your's doesn't encourage others to do the same, which may enrage some drivers.
Best tank= 81.23 mpg on july 1st 2008
SAVE SOME GAS, SAVE THE WORLD!
I haven't been able to find the one I first saw for motorcycles, there is a compeny that makes signs that bolt on above or below your lisence plate that come in "40mpg" "50mpg" and "60mpg" I think they might have said "and having more fun then you" or something like that.
but mpgstick.com sells them from 30+ to 80+ mpg as bumper stickers.
