Some people are such idiots. From the article:
"Yet a slew of emails received by the Tribune on Monday raised new concerns, [including] cattle-car atmosphere that is not conducive to reading or even gazing out windows"
Yeah, this is a tourist train, bring a novel or look at the back of factories and garages... CTA is here to entertain you, that's why "CTA" stands for "chicago enTainment Authority".
"Women with low tops are going to feel uncomfortable with guys standing over them staring at their cleavage in warm weather"
Dress appropriately. Appropriate is a subjective term, but if you don't feel comfortable, it's probably not appropriate.
Toni Apicelli said one of the things she loved about moving back to Chicago from New York, where the MTA trains are equipped with inward-facing seats, was "not having to look at people's butts and crotches on the subway."
Then don't stare. Honestly I see a lot on the train and I just ignore it. You don't have to mentally undress the person just because they're in front of you, you can wear sunglasses, you can look up or down, or you can look at the pocket your wallet is in to ensure nobody is reaching in there to borrow it. Or you can just act like a darn adult and realize everybody has a butt and a crotch and not be a perv about it.
If you've gainfully employed and ever tried three times to board a packed rush hour train on the way to work, you really don't care about anything but getting to work. You're ecstatic that the new cars can hold 120 people rather than 60-70. You feel that your tax dollars are being put to work in a smart way.
