Sweet mercy, bless your hearts. This example is clear and you both seem to be the problem.

The car it's talking about is at a red light, intending to turn right while there is active vehicle traffic proceeding through (the lanes with the green light). There are cross walks at this intersection, as there typically are in non-rural intersections. So the car (or truck, no judgement), which is facing a red light and intending on turning right before their light goes green, inches forward entering the crosswalk that is facing the green lights. They do this so the driver can watch the oncoming traffic proceeding through the green light. They are watching for a gap in that traffic in which they can slip into, during their intended right turn. This brings the car through 2 of the 4 crosswalks. 1 where a would pedestrian has the right of way, the other does not. The primary hazard here is that this driver, the one at the red light and wanting to turn right, is likely not paying any attention to anything on the right. Which could have a pedestrian entering the crosswalk, as is their right of way, and increases the likelihood of an accident where the car is at fault. A concern of this behaviour is the driver blocking access to the crosswalk which, where pedestrians have right of way. This is inconvenient to the pedestrian and can again put them into a hazardous situation of forcing them closer to oncoming traffic to walk around the offending car.

If that hasn't cleared it up for you and you drive a vehicle, please stop driving.
