Earlier quoted context omitted.
In other places cars are supposed to stop for pedestrians even on non crossings, in practice the penalties for hitting and killing them are way lower than killing a person in another situation.
Pedestrians should also take responsibility for acting dangerously. To me it's the same if a driver cuts in front of me and then slams on their brakes, there was nothing I could have done about crashing into them no matter how safely I was driving. If a person runs in front of a moving vehicle it shouldn't be the driver responsible if they basically cut the car off. A car can't stop on a dime. Drivers should be held…
That sounds like a you problem. Why is it up to the pedestrian (who may have never driven a motor vehicle) to anticipate the performance characteristics of this large metal vehicle in the street ?
The UK already has designated areas with no pedestrians ("Motorways" ~= US highways [?]) and it has expended considerable resources closing or diverting at-grade crossings of railways (which obviously have a more extreme version of the "can't stop on a dime" problem). You aren't allowed on most airstrips at all, without special permission, in a vehicle or otherwise - so that mostly leaves cars hitting pedestrians, seems robustly like that's actually always the car driver's fault even if (as we see for "Jay-walking") they'd prefer to pretend it was not.
