Enforcement is not the answer, which amounts to blaming the (potential) victim. The solution is with reduced motor vehicle speed, better infrastructure for bicycling and walking, and thereby reduced volume of automobiles and traffic.
“So, I’ve checked the statistics and, as far as I can discern, none of those pedestrians was killed because they were bumped into by another pedestrian checking their Twitter feed. No, instead, they were all killed because cars struck them. It’s as if the No. 1 cause of deaths on Ontario roadways are automobiles, especially those driven by distracted drivers.”

Girl killed while crossing street Facetiming–WHILE WITHIN THE CROSSWALK. “Now we all tell our kids to look both ways when crossing the street, and not to look at phones. But everyone here is just so convinced that the kid is so totally at fault. Had she been daydreaming, had she been blind, had she been old with bad hearing and eyesight, it might not have even made the evening news. Instead, it just becomes part of the continuing campaign to shift the burden of responsibility from drivers to pedestrians.”
