If you jaywalk across a road with a 60km/h speed limit and get killed because the driver couldn't possibly have stopped in time, I wouldn't really want to blame the driver
Only if you jumped in the field of vision of the car. Drivers are supposed to be able to stop within that field of vision. Driving faster than that is unsafe. If you jaywalk but you are not in anybody's field of vision and still get hit then it is the drivers fault for driving too fast and not being able to stop when they see you in the middle of the road.
