Can the car door be locked without turning off the engine?

[ElizabethRose]

The car door cannot be locked without turning off the engine. The reasons why the car door cannot be locked without turning off the engine: For safety reasons. After parking, the vehicle remains in the same position for a long time. As exhaust fumes accumulate, they are highly likely to enter the car through the air intake. Since the vehicle is not completely sealed, even with the internal circulation turned on, this is unavoidable. If someone is locked inside the car, the consequences could be unimaginable. Methods to prevent forgetting to turn off the engine when exiting the car: Check the tachometer and display screen before getting out of the car to see if the display is turned off; whether the tachometer reads zero; if the steering wheel is raised; and turn on the daytime running lights.
