I actually caught a brief thing on TV about this the other day...this dude's been doing it for years but I felt his driving habits border on aggressive. LOL. For instance, he doesn't hit the brake for corner, etc. I didn't really watch a lot of it because I thought it was stupid and no way am I driving like that to get a few more mpg. I doubt it'll make much difference in my stupid automatic V6 4Runner anyway. I'm lucky to get 16. But I'm anxious to see if anyone does figure out any helpful tips!
