Bravo, well said, apart from a minor point.

How does travelling at a slow speed cause someone to crash?

Two ways:

1. If you drive slowly you will be causing more drivers to want to
overtake you. Overtaking is a dangerous manoeuvre. Even if it's on a
motorway which has 3 lanes and you are on the inside lane, you will be
causing other drivers approaching behind you to change lanes to
overtake you. Once again a potentially dangerous manoeuvre. Safer if
you were going faster thus causing fewer overtakes.

2. If you are driving slowly your journey will take longer. The longer
your journey, the more time you have to lose concentration.
Concentrating intensely can be enduring. And it's no use saying to just
take breaks, because as your journey will take longer, it's likely
there won't be enough time for breaks.

So two reasons why driving slower can be more dangerous.

I would like to see the speed limit on some (if not many) NSL
single-carriageways reduced to 50mph but increased to the same limit
for HGVs too. You'll no longer get "stuck" behind an HGV because
they'll be going at the same speed that you would be anyway. Yes, your
journey would take longer at the times there would be no HGV anyway,
but it would actually be shorter on the times when there is. Fewer
overtakes, fewer accidents.

(Of course, having a 50mph limit doesn't mean you have to drive at
exactly that speed. On a bend, for example, you would slow down).
