The subway

I remarked to my wife last night that the New York subway is an extraordinary source of erroneous legal knowledge. My favorite example is the sign explaining to patrons that failing to give up your seat to the elderly, pregnant or otherwise disabled is a violation of the law (it is not - the only relevant law, to my knowledge, requires the government to provide such seats, not for individuals to get up). Just on a super-quick, lunch time read of the code, it also appears that the signs admonishing citizens that both toy guns painted like real guns and real guns painted like toys are illegal is wrong, as I don't see the latter provision here. And the ads for various personal injury lawyers are a gold mine.
