The smaller lumps of metal and carbon will get stopped by the filter
until it blocks totally, then the relief valve will open, and the
engine
will rapidly die. To check on engine wear, you need to sample the oil,
and I doubt very much that is done at the annual test. With modern
electronic engine control, wear doesn't show in the exhaust emissions
until it's very bad, by which time, it's too late.

Instead of a relief valve, wouldn't a more sensible idea be to simply
cut power to the engine?

Nope, that can cause a serious accident.

Bull****.

Fact.

What do you think happens when a car breaks down?

They don't often lose power completely instantly
and that can cause a serious accident when they do.

What do you think will happen when the engine ****s up because of the crap
going through?

A seizing engine is considerably more dangerous than an engine with no
power.

You don't get a siezed engine that way.

Would you rather drift to a halt or stop immediately?

Depends on the driver and the transmission in the car.

Very easy to do with modern electronics in cars nowadays.

Makes more sense to have a sensor for bad oil and
have the system flash up a warning on the dash etc.

Yes that too.

That instead, actually.

No car manufacturer is actually stupid enough to cut the
engine as soon as the oil pressure warning light comes on.

For a reason.

I only stopped using that car because I was stupid enough
to not bother to fix the windscreen seal leak. I knew it could
get a wet floor after very heavy rain and it eventually rusted
a hole in the corner of the floor and I was too lazy to fix that
given that it had given 35+ years of service fine.

I get a new windscreen every year or two. My car seems to attract
stones flicked up by other vehicles.

You drive too close to the vehicle in front. If you stay at least the
recommended two seconds away outside built up areas, then very few
stones will be flicked up far enough to stay airborne that long and hit
your windscreen.

If everyone left the 2 second gap, only half the number of cars would
fit on the road and they'd have to make them all twice as wide.

Surely with modern technology we could have windscreens which were a bit
tougher?

Fraid not.

Pathetic isn't it.

Nope, no one has invented on that will also be viable in an accident.
