I didn't see it like that all. The car thing was such a manipulative thing to do with Walt Jr and Skyler. Obviously he's keeping up the "good parent" act with Walt Jr like he's been doing since the money started coming in. I don't doubt that he loves his son but he's also clearly trying to keep Walt Jr in his corner and weaken Skylers position. Rebuying the car she once forced him to get rid of along with another equally fancy car and then just rubbing her shoulder and telling its ok, he'll just make up a new lie, everything's cool. So creepy.
If anything the fight between him and Skyler just proved how far away from his original intent he is now. Yeah he wants to keep the kids close to him but it's more about his ego than love. He thinks he's in control and unstoppable. I'm king now, the kids are safe with me in charge. He can have the family, the car, the kids, the perfect everything. He doesn't care about Skylers love. He just wants her submission. She's clearly terrified of him and his touching and he keeps on doing it. Love is not on Walts mind anymore and as soon as Skyler reminds him that he will die he goes into full Heisenberg mode. He doesn't try to repair their relationship. He doesn't spend more time with the kids. He goes deeper into his ego and gives a speech about how nothing will stop him.
To top it off he gloats about Jesse's gift, he treasures it in completely the wrong way. Waves it in her face like here was someone else who hated me. But look what i did to him. He bought be a Rolex now. You'll submit too Skyler. And the ticking watch counting down his lifespan, his family, his meth operation, basically the bomb Mike called him earlier ticking away.
He's gone man. He's got that hat back and he's totally all about Heisenberg.
