And this is exactly the dangerous mindset.

Agreed. The safe way to fly is as if the parachute didn't exist. You
only pull the parachute when the alternative would be death. If you
are thinking about the parachute all the time, it might make you
reckless.

You see the same thing with antiskid braking systems. People know
they are there and assume that the systems will always stop them
safely, even in slippery conditions. What they overlook is that the
systems don't change the minimum stopping distances--they just help
ensure that those minimums are achievable. If the car can't stop
before hitting the tree, antiskid braking won't help.
