“I know more than few friends who found the steering wheel to be of no consequence when enjoying an evening drive with their girlfriend. Sorry it is not physically impossible.”
Try this: Have your wife or girlfriend sit down on the bed to the right of you (you’re driving). Now, try to put your hand on her thigh (you would have to use your right hand, because using your left would cross up the next step), and then put your other hand on her head to guide it to your crotch.
Now, with both hands thus occupied, try to imagine continuing to drive. . .
If I understand the scenario described, they were not parked somewhere (which would have raised alarms in itself), but rather, according to her, she initiated a friendly conversation about seeking a job while they were driving.
Maybe he removed his hand from her thigh so he could use that hand to move her head to the proper position? Just saying.
