This is a pretty funny phrase that I thought about the other day when I was in the car with my mom.
She’s a wonderful woman but her driving is sometimes a bit ridiculous. Add was sitting in the passenger seat (also known as “shotgun”) and I was in the back seat.
My mom drives differently than I would. She’s pretty safe but I feel a bit scared because I think that she always stops later than she should. Sometimes from the back of the car I will yell something like “slow down” or “stop” or “what are you doing!!!!!”
That’s called being a “back seat driver”. I’m not actually driving the car because I’m in the back seat. I’m a “back seat driver” in this case because I’m sitting in the back seat of the car and giving my mom instructions on how to do a better job driving. Everyone hates back seat drivers when they are on the road but I admit to being one sometimes.
I’m sure you’ve had or seen this experience sometime in your life. You might even see it everyday! Now at least you know what it is and what to call this kind of person.
