No kidding? Wow, that's good to know.



I've been coasting a lot in neutral recently, there are lots of hills around here. I find I can coast a significant percentage of my drive to work (like maybe 20%?)

To add another twist to the neutral question, if you coast in gear you'll go slower and have to get back on the gas earlier. If you coast in neutral you can go quite a bit further and faster. But how much gas does idling use?
