It's very easy to tell if pedestrians are walking on a parking lot, so use your pattern recognition given to you by evolution (sic) and don't drive on them.
Personal responsibility, driver!
Not really if the car park is full and other vehicles are obscuring your view. At least being back in you can see a bit better. It's a danger in any type of vehicle.
It's like horses and mountain bikes on shared tracks, they can hear dirt bikes or snowmobiles coming so have plenty of time to move out of the way.
