The Conservatives in Wales lose their last ditch attempt to stop the speed limit change from 30mph to 20mph. The change will be coming into force on the 17th September

I can do the maths, but apparently you refuse to. You're going by what you've been taught about speeding on the motorway, how 80 mph is really very close to 70 mph in terms of time. That doesn't hold true between 20 and 30.

You're not considering anything, you're not arguing the points I've presented, you're just trying to fight me. It isn't working.

If you have evidence that backs up your side of the argument then please present it, like I have with the government's compliance statistics. Don't try to pass off the work for making your argument onto me.

So their key points:

Drivers cut their spacing as braking distances contract. Shorter gaps mean more vehicles can use the available road space, reducing standing traffic.

Filtering at junctions becomes easier too. It is far easier for motorists to pull into traffic travelling at 20mph than at 30mph. So junctions work more efficiently and queues reduce.

Motor traffic volumes decrease since slower speeds encourage active, sustainable and shared travel. Walking and cycling levels rose by up to 12% after Bristol’s 20mph limit[i].

Buses operate more efficiently. The reduced length of queues means that bus journey times decrease, and become more reliable. Buses become a more attractive alternative to the car.

Don't really relate to 20 all that much.

The space in distance between moving traffic is irrelevant, the following distance expressed as time will always be the same (~2 seconds). The space between stationary traffic is the same in both 20 and 30 zones.
Filtering isn't about speed, filtering is about technique. It's about restraining your acceleration and leaving a bigger gap in front. It can be done at any speed - it's what you do when entering a motorway at 70 mph. Reducing the speed limit does not teach people how to filter.
Bristol is a city, this post is about Wales as a country adopting 20 mph limits. I live near Bristol, and many Bristol roads need to be 20 - they're too narrow and there's too much going on (and that's not to mention the potholes..). That isn't true elsewhere in the UK, and certainly not throughout the countryside, even the countryside immediately outside of Bristol. However, even with the 20 limit, many of the roads in Bristol are not built suitable as 20 mph roads, and compliance in these areas is very low. Even buses do 30 in these places.
The efficiency improvement for buses is negligible. Drivers let buses out. Again, this incorrectly attributes reducing speed limits to training drivers how to filter and how to drive in traffic.

If you want 20 mph roads, then build 20 mph roads. If you want drivers to drive better, train them.

Just in general, can I ask what you're hoping to get from this thread? I mean, you're in the Fuck Cars community asking everyone to agree with you that today's driving is okay, that there aren't benefits from slowing down motor traffic and that we shouldn't expect people to act legally. It seems a strange battle to choose.

I'm just calling out bullshit political pandering in a blanket speed limit reduction as what it is: bullshit political pandering that doesn't even really achieve the goals it sets out to do.

I'm not against 20 limits, I'm not against increasing safety of vulnerable road users, I'm not against reducing the use of cars. I want those things to be done appropriately and effectively. This is not that.
