Although their attribution is leaning on the minimalist side.
A light rail station in Portland is accessed from the bridge above it, but Google Maps is unaware that they're connected. Because of that Maps leaves it out of directions; commuting options are completely incorrect. If you manually select it as a destination it will give you ludicrous directions like this: https://goo.gl/maps/XYTZwNiRkipzNHse9
Stranger still, the northbound side of the same station connects just fine.
That's pretty shocking, that station has been there for three years.
