It's not the idle at the stop sign that matters, it's the slowing and and re-accelerating afterward. Idle itself uses a trivial amount of gas - equivalent to around a tenth of a mile for a 15 second idle.
- grogenaut 4y ago10th of a mile at 15 seconds is the equivalent of doing 25 mph. I'd not call that trivial considering you're not doing 25mph.
- ars 4y agoThen my math must be off. 60 miles/hour at 15 miles/gallon = 4 gallons/hour. Idle is like 0.15 gallons/hour. There's no way 25 mph uses that little gas, if 60mph uses 26 times as much.
