Does any car get automatic engine stop while it is standing idle on signal?

Yes, many modern cars have a feature called Automatic Start-Stop or Engine Stop-Start. This technology automatically shuts off the engine when the car is stopped, such as at a traffic light or in heavy traffic, and restarts it when the brake pedal is released or the accelerator is pressed.

How it works:

* Sensors: The system uses sensors to detect when the car is stopped and idling.

* Engine Shutdown: When the car is stopped, the engine automatically shuts down.

* Engine Restart: When the brake pedal is released or the accelerator is pressed, the engine automatically restarts.

Benefits of Automatic Start-Stop:

* Improved fuel efficiency: By shutting off the engine when idling, it reduces fuel consumption.

* Reduced emissions: It helps lower exhaust emissions, particularly CO2.

* Reduced noise: The engine is silent when it is shut down, which can be more pleasant in urban areas.

Not all cars have this feature. The availability of automatic start-stop varies by manufacturer and model. You can check the specifications for a particular car to see if it has this technology.

Some cars may allow you to disable the feature. This is typically done through a button or setting in the car's dashboard or menu.
