Don't have the leaving early part down yet but I'm making a conscious effort to be more accomodating on the road? For a long time I've been annoyed with some road behavior. People squeezing in before me with what feels like half a meter to spare. People not letting me join the passing lane. Until I realized that I contributed to these myself. Because I didn't want anyone to squeeze in in front of me I kept a short distance to the next car which means that other cars were either not being let in (which I hate when it happens to me) or force it by squeezing into way to narrow gaps.

So I decided to deliberately let anyone join the passing lane that wants in. I'm not gonna drive slower as default but if I see you stuck behind a truck I'll fall back enough to make it clear that you can hop over. This solves both problems for me.
