Slowing other pedestrians, endangering bicyclists and yourself, and putting drivers at risk of a traumatic experience due to your recklessness violates the social contract, not fines for anti-social/rude/unsafe or otherwise reckless behavior.
EDIT: Walking while texting or using your phone not held up to your ear? Receive a fine. Doing the same while driving? Lose your driver's license. These are the only ways to fix behaviors that show no regard for others causing a safety hazard.
If you have a substantive point to make, please make it thoughtfully; if you don't, please don't comment until you do. This applies even when someone else is completely wrong, since a reply like this won't convince anyone anyhow.
I do fear there will be an uptick in problems with EVs, though, that don't have pedestrian warning sounds added and people not looking because they hear nothing and expect to hear an engine (experienced this a little bit in parking lots during my time driving a Leaf). But we'll see what happens I guess.
A lot of the time people are looking at their phones, and look as if they aren't intending to cross, and in the midst of looking at a screen, suddenly out of nowhere, step into the street and start crossing, eyes still glued to the screen.
In several states, if you're above a certain age (to exempt children) and walk into the path of a moving vehicle outside of a crosswalk, fault will be assigned to you and the driver in equal amounts (unless the driver is speeding, in which case they accumulate more fault).
At least in Britain, roughly the first driving lesson begins with looking all around for other road users. Speed must be reduced if there's an increased risk of inattentive pedestrians, such as near parked cars around a school or houses.
However I don't think fines are the right way to go. Signs and advertising campaigns would be better. Fines just violate the social contract. You're also not really hurting anyone else but yourself. In the fight or car vs person, the car is going to win .. I mean, unless you get hit by a cyclist.
