This is just an anecdote, but I've alerted Google to a particular mistake in Maps multiple times and it's never been fixed.

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 worse than weird, that's downright dangerous. There are no sidewalks on that street, and cars travel at 55-75 mph on it. There's also no way to get from the street to the station; the overhead bridge is the only way.

That's pretty shocking, that station has been there for three years.

It gives a disclaimer that walking directions might not reflect real conditions.
