| The radial numbering can be a useful ‘signpost’. As an anti-invasion tactic during World War II, a civil defence measure was to remove many road signs. That’d stop those nazis in their tracks. So to this day, I find the UK a difficult country to navigate by signs alone as they are often absent at important local junctions. In many other parts of the world, you can trace your way from a major destination by signs at forks/exits. In the UK, this often only works on ‘M’otorway routes. With satnav now ubiquitous, much local signposting tends to deplete over time, unless it is to control traffic flow. |
This is the opposite of my experience as well - I've driven in many countries (currently live in NZ), and despite its quirks (not saying it's perfect), I've found using UK road numbers for directions very easy in general compared to other countries that have highways that re-use road numbers in multiple states or something, which has at times caused confusion.
