The ambulance bay is located right outside the emergency entrance to a&e which in any emergency you would drive straight to (if you had a passenger). If not you would throw it in any space in the car park.
TBH most of us know how to park properly even if in a rush as we know how to swing into a space, obviously some don't but in a public car park in a hospital you would let the above go assuming it was someone rushing to a loved one not in the right frame of mind.
This however was in a staff car park, l again if it was a a doctor/nurse called in or rushing to a major op, again fair enough and if the culprit hasn't come to light again you would let it go on that basis.
Unfortunately in this case it's come to light that it was neither case and more care should've been taken, it appears as if the driver was more used to a smaller type of vehicle by the sort of parking displayed and should've spent a few more seconds backing out a straightening up. It's not that difficult.
