Let's not forget modern cars have "throttle adaptations" and will automatically compensate for the driver's lack of throttle input. If you just release the clutch pedal slowly, the engine will rev itself enough not to stall and the car will start moving.

I've also noticed you can release all pedals while driving these days and instead of eventually slowing to a stall, the car will only slow until it's happily rolling along in gear at some sort of very slow minimum speed. I presume that's the same feature?

  • Pretty much any non-carbureted car should do that. All fuel injected cars have some mechanism for controlling idle, which involves some kind of valve bypassing the throttle (for mechanical throttle linkages) or just directly actuating the throttle blades (for drive-by-wire systems). There should be enough travel in the idle circuit to allow a tiny opening to keep idle low enough once the engine is warm, and a large enough opening to keep idle high enough to prevent stalling when the transmission is engaged.
