When a distracted pedestrian bumps into another, it is resolved with a "sorry!". However, a collision between a pedestrian and a motor vehicle means broken bones or worse.
Since the car is what turns collisions into tragedies, education campaigns should primarily focus on reminding drivers that they are operating a vehicle that can easily maim and kill, so they must be in the lookout for unprotected people.
Want to remind children to look both ways? Great. Because they are children. But when it comes to adults the campaign should remind drivers.
