This is a toddler argument. Driving is a time-consuming chore in most cases, so people zone out, get distracted, don't pay attention to things that are harder to notice and are much more vulnerable than the vehicle itself. We depend on driving for better or worse, doesn't mean we can't make roads safer for pedestrians.
When compared to the EU (no right turn on red), US stands out as an extremely unsafe country for pedestrians, with pedestrian deaths actually increasing year-over-year. Sure, it's not all attributed to the right turn on red law, multiple new regulations are needed.
