Ideal would be speed limit based on the road. I drove some "roads" in Ireland, where speed limit is 80km/h but driving faster than 40km/h is daredevil behavior.

Ideal would be speed limit based on the road. I drove some "roads" in Ireland, where speed limit is 80km/h but driving faster than 40km/h is daredevil behavior. And don't mention the fact that some roads are not large enough for crossing another vehicule, but it can happen (and sometime the locals drive at 80... A lot of surprise braking !) But it's obviously more difficult to implement, and more difficult for the speed camera management. Yet, it would be better and certainly safer than the "one speed for those type of road fit all" (to be honest, this proposal is more advanced than other countries where you hav three or four types of speed limit, and that's all)

This! Some country side roads are very narrow, surrounded by stone walls on both sides. There are no sidewalks obviously.

The road from Head of Dunloe down into the Black Valley is 80km/h. You'd be lucky to push 40 on the straight sections!

  Hah. That's the one place I've ever had a car pull over to let my bike by.

    ditto :-) Those tight switchbacks are fun too... I'm based nearby so Dunloe/Black Valley/Molls is a regular cycle route for me

> and more difficult for the speed camera management. In Germany the police needs a specific reason for placing a speed camera. Like a statistic that there are a lot of accidents on that street at that particular spot, or that the street is exceeding noise levels. So, they already have to take into account every individual speed limit; and if the Germans can do this, the Irish can certainly too! :)

> Ideal would be speed limit based on the road. You kinda already have that, but you cannot make it too confusing for drivers. German example for roads between cities: No sign at all, default speed limit 100. 70 sign (usually with a reason e.g. winding road, trees etc). 50 sign or even 30 sign, no overtaking sign, e.g. narrow road, pot holes, intersections. Works, but can be quite stressful to keep track of particularly for new drivers. Issues with that: The locals who drive 80 will complain that there is no reason for a 40 sign and laws tend to require a reason (e.g. speeding tickets are cancelled retroactively if the state cannot justify why there needs to be a limit). Too many signs and cases confuse drivers and are easily missed. Installing, replacing, repairing and keeping track of signs is expensive. Too many rapid adjustments also don't work well with slowing down, accelerating, reading signs etc., so it cannot be too fine grained. That is why there are "one speed for those type of road fit all" approaches: to keep matters simple.
