[PaleMelanesian]

There is one case I've been in. Stopped, waiting to make a left turn across traffic, from a major street onto a side street. Driver behind didn't seem to notice brake lights AND turn signal. A quick acceleration avoided a rear-ender. Now I leave it running and ready in those situations.

Any other time I'm stopped and engine-off, I'm in first with the clutch pedal depressed. It's a quick crank-release to move.
