At my old job, I would've never needed it as I only had bad traffic a couple times in 8 years. At my current job, I would use it every day as my commute involves a major highway expansion and traffic can be horrible. Some weeks, I take a different way to work each day and yet a different way home. Today it routed my to a new section of the highway that just opened and even with getting stuck at a light, it was much faster than the alternate route that I've frequently taken over the past year.
I agree about the climate conditioning. I do NOT want that as I only need to condition my car as few mornings per year. Hopefully they will be it programmable by day and we can disable all days.
