Quoting myself from my dynasty story set in Bridgeport.
"The subway system SUCKS! I hate it, I moved Romeo in so I could steal his Vaguester, that's how much I hate it. It's awesome for long distance travel, don't get me wrong, but sims auto use it to get down the block if they don't have a car, and it takes the same amount of time to cross the town as to cross a block. Which means sims could jog there much faster! Which is what I did during my first failed attempt before meeting Romeo Rake."
It's mentioned, just most don't play in Bridgeport, but believe me, you are not alone in thinking the public transport there is super crummy
