Well yes but it's also the responsibility of the pedestrian to demonstrate intent to cross the road if they do in fact intend to cross.

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.

There is absolutely no excuse for a car to hit a pedestrian in or at the end of a crosswalk, regardless of “signaling”. The car should be driving slow enough to make this impossible, and for the worst-case scenario to be the pedestrian walking into the car.

The person in the car should be looking where they're going, but they expect a clear roadway, not random pedestrians stepping out without paying attention.

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).

The driver should certainly not expect a clear roadway.

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.

Where I come from (France) and where I live now (Japan) the laws are quite similar in that, as a driver, you have to be "in control" of your vehicle at any time. Meaning that you need to be able to stop it to avoid any unexpected event. Quite sensible if you ask me.
