I completely agree, but this still doesn't fix the problem of motorists "not seeing you" when they are looking down at their phone.
I've nearly been hit a few times by turning cars... while wearing high-viz and reflective clothing... riding a bike that's high-viz... riding on tires that have reflective sidewalls... while using a flashing front light, a solid front light... equipped with a flashing rear light... and riding in a slow, predictable way.
Being visible only works on those who are paying attention around you, and these days that means fewer and fewer people.
