I love taking an hour or more drive with someone. It's a wonderful opportunity to catch up or get to know somebody from scratch. It's free from distractions, with just enough happening out the window to be interesting. It's a form of intentionally taking time for a discussion.
What's even better is when this type of casual discussion is ritualized. A phone call on the way to work, walking the dog together in the morning, and making dinner together are a few good ways. Rather than dulling the relationship, these rituals make the connection stronger.
In a way, this is the point of recurring meetings at work. It seems to work pretty well for one-on-ones, not quite as well for larger groups.
