Theres no other way of really hearing voices in your ears. Loudspeakers
don't do that.
BTW is there anything you do like?
I'm not apathetic... I just don't give a sh** anymore

So enlighten me.
In what circumstances do _you_ think an alert and attentive driver can
head blithely towards a low bridge in a vehicle that was almost certainly
visibly tall when they got into it - without even the slightest
expectation of "issues" crossing their alert and attentive mind...?

I've seen some, thank you.

When their brain is busy processing a (perceived) higher-prority
input. The brain is a single-channel processor. It cannot process
two things at once, but most people are unaware of that fact because
the brain is good at deferring processes without us being consciously
aware that they have been deferred. Many actions that we carry out
whilst driving are automatic and do not require processing power and
so it can appear that we are multi-tasking. Simple *familiar* warning
signs would not require processing. Comparing two numerical values
and determining which is the higher value *does* however require
processing, and that will automatically be deferred if another task
requiring processing power is being undertaken at the time. For
example, perhaps a group of people are standing near the edge of the
pavement and the driver needs to process the probability of any of
them stepping into the road.
If you want to see how many occasions during driving the brain's
processing power is needed, simply ask the driver to describe his
house to you in detail next time you are a passenger - but keep your
eyes closed. Because you cannot see what is taking place, you will
notice something that you usually would not notice. Every now and
again, the driver will stop talking - often in mid-sentence, and then
resume again a few seconds later as if there had been no break in his
speech. Those breaks are when something with priority has taken over
the driver's central processor.
And if you believe that you are an exception and are able to process
two different things at the same time, try reading a newspaper article
or doing a mental arithmetic exercise whilst verbally describing how
to boil an egg.
