Can you remove the ignition key without turning off the car?

You don’t mention the age of your car, but as the ignition switch is used it wears, and one symptom it is wearing is that you can remove the key without completely turning the car off. Next time this happens, put the key back in and make sure the ignition switch is completely turned in the off position.
