And that the cause can be addressed by regulation. There's no regulation that will protect from bad actors so designing the system to cater to them in extremely specific ways just creates more red tape for normal people.

Said another way, mandating safer intersections will apply to all motorists and pedestrians equally when they interact with each other at a crossing, but if the bus driver forgets to take their crazy pills that morning and the voices in their head say to run someone over, there's no amount of safety systems or auto-stop that are likely to really prevent harm from being done.

In most Western European nations however, we are fully capable of designing and enforcing travel networks that should rarely produce fatalities when it comes to interactions between cars and pedestrians. The reason many countries don't is a matter of political will.
