Re: Yes well...
"- "the road" includes roadsigns, vehicles, hazards off the road. Road signs are designed to give you information in your peripheral, drawing your attention to them and helping you read the road."
The more signs you see, the less you notice. Using less signs gives greater impact to remaining signs. Putting more signs up doesn't make it safer.
"- If you can't tell what speed your doing (roughly) without staring at your speedo, you shouldn't be driving, although you say you can do it without a sign? Cursory glances are no more distracting than the cursory glances you should be making in your mirrors."
Victorian police are nor allowed to hide in the bushes at the bottom of a hill and book you for doing 61 in a 60 zone.
"Speed zones are incredibly simple. Can you see a bunch of streetlights (3 or more)? Then it's 30. Can't see a bunch of streetlights? Then national speed limit applies. Unless told otherwise. You're told otherwise by gated entry (two signs each side of the road), and reminded, roughly, every 15 seconds of driving by a repeater sign."
Not in Australia. We have 40,50,60,70,80,90,100 and 110 zones. The speed zone can change depending on time, weather and other vehicles. You can be in the middle of nowhere in a 100 zone and suddenly hit a 60 zone for no obvious reason. The police like to hide in these areas and all it takes is missing one sign.
"I'll assume this is a correct stat. However, most car accidents happen in urban areas (volume of traffic), but are largely sedate, mainly due to all the points above. Most fatal car accidents happen on country roads, specifically due to them being narrow, harder to reach for emergency services (distance if nothing else), poor mobile signal to call for help etc."
It's the fact that the roads around here are poorly maintained, windy and overgrown with trees. Trees are not very forgiving if you come off the road.
