"don't pick a bike if its seat is twisted around backwards. That's a sign that a previous rider found the bike busted." -(from SamtheBrand's answer to How to choose the right Citi Bike? )
Can someone please elaborate on this rule please?
Is it widely known and used?[1]
Is this some sort of official or unofficial rule communicated somewhere?
Is it specific to Citi Bike program or generic to any bike rental/sharing ones?
[1] - I have ridden Citibikes almost every weekday for over a month in NYC, and have never observed a twisted-around seat. But I didn't set out to find one so it's not much of an evidence.
