Update from the principality. Sticking to the new 20 mph default limits on most urban roads is causing unprecedented amounts of seethe from Audi, BMW and Range Rover drivers. It’s best when they lose patience and overtake and I smirk at them when I pull up beside them at the lights. Journey times completely unaffected by this, but some people struggle with the concept of limiting factors. I’d highly recommend the Scottish government doing this in the interest of annoying arseholes.
