���������� ���� ������ - the car is asking you to shift to second because the revs are too low at 1200rpm.

�es��������� ���� ������ - (strangely) the car is asking for 3rd, because the revs are high enough to change up to third at 1800 rpm to maximise efficiency.

���������� ���� ������ - car is perfectly fine.

This was done in a VW Golf with a 2.0tdi Bluemotion(edit) engine, a fairly normal car. And one that should have enough torque to pull a car at lower revs.

But it's not happy. This was done on the flat. If the road starts to incline, you're going to need to select 2nd. An auto box will be working overtime.

... and there goes any reasoning by Welsh Labour that 20 is better for the environment.

I can't say what this will do for engines and gear boxes - there will be a lot more engine lugging (strain). If you have a diesel, you really need to change if you only drive in areas that are 20, it will kill the DPF.

This style of driving is going to mean a lot more shifting, more drifting above the speed limit and an added distraction that will require extra concentration. You'll probably also see a lot of stalls.

Further, everyone will be bored from driving so slow and will pick up a mobile phone. So it's not safer.

Their argument "being hit at 20 is safer than being hit at 30" is correct. But it doesn't factor real-world logic. If drivers are distracted there is a huge increase in dangers, especially reaction time.

���� ���� ���������� - in the real world, on the whole, no.
���� ���� ������������ ������ ������ ���������������������� - you'd need to see some more accurate data, but spending 1/3 more time in an area at similar or higher revs... sorry, but no.
���� ���� ������������ ������ ���������������� - maybe. Around schools or housing estates for sure.
���� ���� �������� ������������������ - Ł33m to implement and Ł4.5b (as admitted by the WaG)... ummm no.

Welsh Labour need to be questioned on their science and met with the real facts. Nobody in the the Senydd is doing this.

Can a petition be started to question their facts?

Please feel free to question the science here. But don't repeat tests on the road. 20 zones make a lot of sense in a lot of areas, but a blanket roll out is nothing short of stupidity.

Please, please don't vote for Welsh Labour in the next election. You don't have to vote Tory, just don't vole these idiots back in.
Fair play. That made me laugh. 🤣
