It's more like blaming the users for failing

pickup trucks in a row drive by).
Someone concerned with safety will _always_ block the tires with chocks. You
see that done with aircraft all the time. Of course, people who own and operate
aircraft are a lot more concerned with safety than people who own and operate
cars, but the point is that safety is not Someone Else's responsibility, but
yours.
