In case you haven't noticed, it's a little bit rainy out. Or pouring, depending on your perspective. If you're in a car, you'd probably think it was a little bit rainy. If you're walking (or, I'm so, so sorry) on a bike, I'm guessing you'd go with pouring.
So if you're, oh, I don't know, walking home from the grocery store with your bags in one hand and your umbrella in the other, standing at a stop sign with puddles gathering faster than you can step back is not exactly high on your list. In fact, you'd want to cross the intersection as quickly as possible to get out of the rain.
Unless you're singing in it.
Which seems unlikely.
Not that I'd have any recent experience with it or anything.
So say you're this person, let's, for ease of identification, call her "Me," you might have come up with some observations while playing chicken with a car in a clearly marked crosswalk at a stop sign. Me realized, for example, that most people operating said cars don't really seem to care that they're inside a roofed vehicle while a person, such as Me, is exposed to the rain, with it blowing under the umbrella and soggifying the groceries.
Windshield wipers blazing, their little car cockpit nice and dry, they're thinking, "man, stop signs are stupid, why'd I even slow down?"
I'm guessing. I can only infer from what I see.
Drivers of Chicago, for heaven's sake, if it's raining, let the pedestrians cross the street, instead of zooming through and drenching them with puddle water (please note: Me was not drenched in puddle water; it was a hypothetical enhancement for effect. But it could happen). Do not make the pedestrian step out into the street and stare you down, willing you not to hit her.
Yes, blue Honda, that's right. I'm talking to you.
Pedestrians aren't cardboard figures designed to pop out and test your reflexes. They are actual people who probably want to spend as little time getting soaked as possible. The thirty seconds it might take to let someone go means they'll be out of that downpour that much sooner, and then you can feel good about not running anyone down.
Even though not running anyone down is generally required behavior.
Still, it's a start.
