“Nobody goes there anymore, it’s too crowded.” -Yogi Berra

It's a quote from Futurama: https://www.youtube.com/watch?v=KIrlZSYB6tE

(Nobody drove in New York, there was too much traffic)

That's the joke.

well if traffic is generated by 1% of the population and if that traffic is already very crowded, it's almost true. that would mean the streets are very narrow.
