Reminds me of a story: two years ago I was riding my bike, doing a 45 miles ride from Montreal to Dunham. I was following Google Map's directions and it led me inside a Canadian Army base (Farnham). I saw modified pickup trucks full of guys with rifles about 100 metres from the entrance which said "Keep out" and Google wanted me to go there. I didn't. They changed it now.
I sent in a report sending bikes through a highway tunnel in Boston, took six months but received a message they made the correction.
