I would have thought speed was a factor in all RTAs. I've never heard

Yes, but is the difference between the actual speed and the limit the cause?

We have a road down here that I reckon I could take at a ton (given road
closures - there are side turnings) yet several people seem to have
driven off it and crashed. So they've imposed a 50 limit. I have a
feeling those crashes weren't under 60 either - the most recent
(non-fatal) one was over a ton, and drunk too.
