Conversely, as a cyclist, Google Maps infuriatingly will refuse to route you along an expressway, even when it's the shortest or only route without a huge detour. e.g. Lawrence Expressway where it crosses in an underpass under Central Expressway. This is a long-standing known issue with Google Maps routings for cycling mode.
