Ideas for New Features Car Companies Should "Invent"

Every once in a while we get a new feature that seems obvious once you've seen it. For me recently it was the hill-holder feature that a lot of manual transmission cars now have. I'm wondering what ideas might be out there for features that we haven't seen yet? This might include features that are very rare (and after all few of us know the entire history of every model, so something may have been done but you just don't know -- no worries!).
