Almost every situation has both primary and secondary safety. You

Don't be silly. The number of road accidents due to brake failure is
tiny. And pretty well every modern vehicle has dual circuit brakes
anyway.

The latter is a way to increase the primary safety, and annual MOT
tests rub that home. The lack of brake failures is a success, not a
problem.

What Dave is overlooking is that brake "failure" is not just a
mechanical issue. Failing to notice that the klod in front has come to
rest due to a queue of traffic on the motorway, and biffing into him, is
also a brake "failure". Which is when the secondary safety kicks in.

Now I understand where you're coming from. Failing to operate the brakes
is brake failure. No wonder you were so easily taken in by Brexit.

Having jointed steering columns is another example, resisted by Detroit
IIRC even though there were plenty of road accidents in the US where
the driver was speared by the steering column.

Detroit stuck with steering boxes when the norm elsewhere became steering
racks. And they are situated differently.
