Imagine yourself driving a car and and spotting someone on the sidewalk. You stop the car beside him and want him to get in the backseat. You say something like "Hey, get in." with a nod of head that indicates that you want the person to get in the back. It is 'the nod' that I am stuck with.
Also I know the same kind of gesture and motioning can be done with just eyes too but I don't know how to write it.
What I really want the reader to imagine is someone just briefly jerking their head in the direction of the back door. But that is not really possible if the person is driving the car. But it happens! In real life! I don't know if you even understand the question. But if you do, please help me write the scene.
I am including the actual piece that I wrote ( that I am sceptical about) below:
The car came to a halt beside me.
“Let's go for a ride,” he said, throwing a glance over his shoulder to the back. “Get in.”
