Good to hear you are settling in. Personally I'm not into dressing up too much for work. I could wear jeans and t-shirt to work, but I choose not to. I just don't go as far as a tie or suit. Have you found some podcasts to listen to on the drive? That could be something to post about. I have a few guitar ones I enjoy, but my commute time is pretty short these days
I find the suit helps separate home and work - plus I never get dressed up for anything else so it's nice to be a little different :) Smart jeans are allowed and a tie isn't compulsory. Officially it's 'smart casual' but I tend to air on the smarter side.
I've been loving 60 cycle hum recently but haven't listened to it on my way to work yet.
I can recommend No Guitar is Safe and Chasing Tone. I listen to various tech and science stuff too.
