Male abuse
Male abuse?!! 
She makes a polite request: he ignores her.
She protests at being ignored: he ignores her some more.
She shouts at him: he responds.
Everyone is speaking and having a nice time.
She interrupts. DH and her sisters try to carry on their nice conversations.
She selfishly interrupts some more.
She throws a pathetic tantrum.
She shouts, ruins the nice atmosphere of the car, and stops their conversation.
DH tells her off for his rude behaviour.
He's acting like a dodgy stepfather
Tell us about this dodgy stepfather category you speak of?
If she can't get it being polite and respectful but only by shouting, what is the logical thing for her to do?
On what planet is interrupting, stopping everyone from doing what they are already doing, demanding everyone does what you want to do and then throwing a tantrum, "polite and respectful"? 
Yes, she's looking for his attention.
No, she's wanting the world to revolve around her. What she wants, she gets, she thinks.
She's looking to connect with him, to have a relationship with him, to share her thoughts and ideas.
No, she wanted to force everyone to listen to her music.
Why is he ignoring her?
Because she rudely interrupted him.
If he engages in conversation with her, she won't need to shout and he won't need to get angry.
If she waited instead of interrupting, she wouldn't need to.
If she didn't dictate to everyone around her what they can and can't do, she wouldn't need to.
If she hadn't thrown a tantrum, she wouldn't need to.
The solution is in his hands. She's trying; he's not.
She is the cause, his telling her off is the effect.
If he can have a conversation with DD2, he can have a conversation with DD1.
She didn't want to converse. She wanted to spoil the conversation with DD2 and demand everyone listen to what she wanted to listen to.
A girl or young nearly-woman learns how to expect men to treat her
A 16 year old brat needs to stop behaving like a 5 year old.
This is vitally important and it's nearly too late now she's 16!
Could well be right here. Her behaviour is terrible.
If she ends up being vulnerable to make abuse it will be because he taught her that was all she was worth; all she deserved. 😢
OMG.
