That's for someone expecting something to happen and mentally prepared
to react as soon as it does.

anyone who is driving should *always* be expecting something to happen
and mentally prepared to react as soon as it does.

So you drive around expecting your foot brake to fail. At the same
time you are prepared for red light runners. How do you cope with that
while watching for approaching traffic crossing over into your lane?

i'm prepared for anything that might happen.

Your nerves must be totally frazzled.

not at all.

and people wonder why there are so many collisions.

**** happens when you least expect it, whether it's mechanical failure
or a kid running into the street or an idiot running a red light.

How do reconcile "least expect it" with "should *always* be expecting
something to happen"?

they're the same thing.

Haw! You are 'least expecting' it, i.e. not expecting it, at the same
time you are always expecting it.

when it does, you don't have time to decide what to do. a split second
can make all the difference and you don't get a second chance either.

The SAE figures are based on John Doe
trundling down the highway and having a dangerous situation suddenly
presented to him without warning. The first thing John Doe has to do
is to recognise that he is being presented with a situation to which
he has to react. Only after that does the reaction time start running.

john doe needs to stop driving, as he's putting everyone in danger.

So you expect instaneous recognition of an unexpected hazard?

i'd like that to be the case, but realistically, i don't expect it from
others.

Even if you are a digital robot you will not be able to literally
instantaneously recognise anything, whether a hazard or not. Would you
be better able to grasp the concept if I used terms like 'delay' or
'latency'?

That's why I referred to it as 'perception/reaction' time. If you are
driving down the road and have cause to brake and then, in the midst
of braking you have your brake system fail, you first have to perceive
that you have a situation to react to. You then have to work out what
to do about it and react. I would expect that it would take you at
least 2 seconds from brake failure to you applying the parking brake.

not for me it won't.

the moment i apply the brakes and nothing happens is the moment i
engage the emergency brake and/or downshift in at most, a half-second.

How do you change gear and apply the parking brake simultaneously with
the same hand?

who said simultaneously? obviously one will precede the other.

the point is that there isn't a 2 second delay to figure out what to do
and when. it's an automatic response. it's a reflex.

Aah. You _are_ an automata.

i'm not the one who isn't grasping the concept.
