It could be why.
It could also be from people staring at their cell phone and walking down the road. I see it all the time. I've seen people walk right into intersections against the light.
Maybe, it's even both, because while I can believe large cars aren't helping... I surely know staring on your phone, walking, and not paying attention is just plain dumb.
You know what's way worse: drivers using their phones when driving. If you drive in a way that you kill a careless pedestrian it's a problem. It's cars and drivers almost exclusively.
The NYC DOT did a study on this a few years back and found it not to be the case:
> Reports of device distraction are scarce in the New York City and national fatality data, and estimates of annual mobile device-related injuries are dwarfed nationally by pedestrian injury estimates where pedestrian distraction was not cited. In short, despite growing concerns, DOT found little concrete evidence that device-induced distracted walking contributes significantly to pedestrian fatalities and injuries. https://www.nyc.gov/html/dot/downloads/pdf/distraction-shoul...
