How do I make her feel like I'm NOT treating her like a child?

I'll stop telling her I had a good day, goodnight will be enough. I'll just say "thanks" when she does something nice.

The being treated like a child issue seems to be stemming a lot from the use of the car but it's getting cold here and I can't keep using the motorcycle. I'm trying to coordinate stuff with her but she's so in those mode of "I don't have to report to you" that she doesn't share much info with me until the last min, expecting to leave me stranded at home while she goes and does whatever. When I step up and say that from a pratical standpoint I need to know in advance so we can figure out rides I get the "you're treating me like a child" attitude. If I take the car away I'm going to get the "I knew you'd do this, you're a dick and don't care about me or the kids".
