I don't give a stuff that Trump didn't help Melania out of the car, or introduce her to Obama before he shook hands with him. Neither of these actions are rude or unusual.
Thing thing that jars is that he couldn't wait a few seconds for her to come round the car and join him so they could walk up the steps together. It looks uncaring.
Of course, it's entirely possible that before the car stopped she'd said to him "Don't wait for me, dear, I'll be right behind you.."
