The only non-arguable definition of "too fast" is whether or not the
vehicle was exceeding the speed limit. That can be precisely measured.
Everything else is subjective.

You can precisely measure the distance that the driver could see and the
stopping distance of the car.

Rubbish. The stopping distance is an average across a range of cars under
certain conditions.

One cannot say that this applies to a given car under all conditions so
it's a notional value.


If the stopping distance exceeds the visibility distance he was driving
too
fast whatever the speed limit.

Irrelevant. This then enters the realms of opinion.

No it is a fact that he was travelling too fast.
The question about speed is purely physics and nothing to do with opinion at
all.
The only opinions are about him being competent and if it was a reasonable
thing to do.
Its just an excuse to avoid hard thinking to say the speed is opinion.


It is important to remember that we operate variable speed limits.. its
the
safe speed or the speed limit whichever is lower.

Except that "safe speed" is not defined, making the statement meaningless.
