20mph limits in Wales - with brake testing! What's occurring?

The default 20mph speed limit change in Wales is causing horror and outrage. I take a measured look at the thinking behind it, and do an exciting brake test demonstration in my Citroen 2CV! The change is effective from 17th September 2023 so don't get caught out. #20mph #wales #cymru List of links: Welsh Government: https://www.gov.wales/introducing-def...
