ELI5: why does a car's steering wheel sometimes need to be twisted/pulled to get the key to turn in the ignition?
gpt
There is a pin in the steering column that prevents the wheel from turning if the ignition lock is engaged.

Sometimes when you park, the car settles into a position where it’s resting on that pin. You can’t turn the ignition because the pin won’t disengage.

Turning the steering wheel releases the weight on the pin, and then you can turn the key.
