Maybe I wasn't clear, I'm trying to understand how you took my reference to traffic travelling at an appropriate and safe speed and read that to assume that could only mean joining a motorway at the maximum permissible speed.

Agreed.
Agreed. If they join the motorway at 70kmph while the traffic in the left lane is travelling at more then 70kmph then they are driving dangerously.
Not if they have just entered their lane right in front of them.
No, I'm describing a car moving with the flow of traffic which is then forced to slow by a dangerous driver entering their lane at a lower speed.
I have.
Road death statistics are measured by accidents per mile/Km travelled. Using that measure the M50 is the safest main road in Ireland. Using that same measure this is a far safer country to drive in than it was at any time in our motoring past and we are twice as safe as the USA.
All traffic entering any motorway should use the slip road to accelerate up to the speed of the traffic already using the lane they are entering. That's what the slip road is for. It's one of the features that make motorways so safe.

Except for where the slip roads go uphill.
You have an example? They are usually designed to ensure that traffic has sufficient space to accelerate up to speed. I've never seen one that merits a grade warning sign but I certainly haven't seen them all.
When joining the M8 at jcn 3 southbound (Ballacolla) there is an initial uphill gradient. But, in my opinion, there's also a sufficient amount of level slip road lane to allow for the required speed to be built up.
That said I've only driven it in a moderately powerful car (150bhp)

I can think of at least 2 others on the M9, Castledermot (both north and south) and also the previous junction where the services are. Both have decent length slip roads and plenty of time and space to accellerate so being uphill shouldn't be an issue
One of the reasons the M8 drops to the N8 at Naas and further north, despite the road continuing to be a 3 lane dual carraige way is that the slip roads are not long enough to allow traffic to accelerate to potential motorway speed
All traffic?
Some traffic types have a lower speed limit than cars - what should HGVs and anything pulling a trailer do considering they shouldn't accelerate to 120kph or even 100kph (I realize many do).
Yes, of course vehicles shouldn't exceed the speed limit.
Why are they almost always marked at slower speeds then? For example the slip leaving the M1 to the M50 is 60kmph?
There are plenty of examples of slip roads being lower speed than the road you came from AND the motorway, not just this one.
That's an exit, the context here is about being able to accelerate up to the speed of other traffic while joining the motorway.
THE JOINT COMMITTEE on Environment and Climate Action is meeting this afternoon to discuss the impact on carbon budgets arising from the growing trend in car sales towards heavier and larger vehicles such as SUVs.... while Ireland’s taxation system for vehicles is emissions based, some countries base their motor taxes on vehicle weight.

EVs would pay more taxation that dirty diesels if it was based on vehicle weight.THE JOINT COMMITTEE on Environment and Climate Action is meeting this afternoon to discuss the impact on carbon budgets arising from the growing trend in car sales towards heavier and larger vehicles such as SUVs.... while Ireland’s taxation system for vehicles is emissions based, some countries base their motor taxes on vehicle weight.

The taxation should reflect the externalities of the vehicle in question. The diesel should have higher taxes due to the effect of pollution on people and the environment. Heavy EVs should have a higher tax based on the road wear/damage caused by their weight.
Road wear isn't the issue with heavy EVs, the vast majority of usage related wear is born by the tyres and brake pads & discs. The challenge is the additional carbon/ pollution involved in their production and increased energy consumption in moving a heavier mass.
Well, the price of every single thing you buy is influenced by the 'externalities' of regulations and taxes. I'm just not sure what point you're trying to make there, but let's ignore road wear as a factor on which to tax EVs, it's negligible.
Of course they're not, that's not how most tax systems works. Consumption taxes usually don't come close to covering the costs of the service with the shortfall being made up from other sources of funding to the exchequer.
Adjustments to vehicle taxation is designed to influence consumer choice, it's not a cost play.
