I’m not sure if traffic is “convenience” at this point. At least where I live, it’s a nearly essential piece of functionality.
In fact, for local driving it’s often the only reason to use a map app. I already know how to get to most of the places I want to go, I just need to know the best route to avoid traffic now.
Often things like this are intended to be support for something else. Maybe there’s something nearby that’s hinged and can fold down on to it?
