Maps, especially when used for real time navigation, are the poster boy example of what Bret Victor means when he says "Interactivity Considered Harmful". [1]
Interactivity is a failure state of software that could have predicted what the user wants from context and past behavior, and tailored the display and presented it to them without being asked.
"Further, the user might prefer to learn information while using her hands for other purposes, such as writing or eating or stroking a cat [or driving the car]. Each time software demands the user’s hands, this activity must be interrupted [at the risk of causing an accident]. Finally, the growing prevalence of computer-related repetitive stress injuries [and using smartphones while driving] suggests that indiscriminate interactivity may be considerably harmful in a literal, physical sense."
