I'm absolutely more relaxed when I take the train in versus driving, even though I have to get up 30 minutes earlier to do so. People at work keep saying "That's nice for now. And then you'll drive again in the winter, right?" Um, no, it doesn't work that way. I like having the time to ease into the morning, and then to decompress in the afternoon. It's carried over into my life outside of work, too. I now look for ways to avoid driving, arrange for someone to pick me up, whatever I can do.
