Well earlier this week I put tufts on the back of my car, and an interesting phenomenon happened...
Instead of tailgating me and then zooming off (passing on the right, you didn't think people here follow rules did you?), all the other cars on the road slowed down (to the speed limit, which is how fast I was going) to get a better look at my tufts!
If everyone on ecomodder does this, imagine how much of OTHER people's fuel we'll save like this.
