About the new rules, the public will learn when they violate them. And that brings money into the treasury. Win win for the government
I'll digress for a bit and explain the rôle of the UK Highway Code, and you'll see that particular, understandably cynical, view of the situation doesn't actually pan out. The Highway Code has, currently, 310 "rules". Some of them have the force of law and those laws could attract penalties if broken e.g. you must stop at a red traffic light. Those rules use the the word
MUST in bold capitals to mark them out. Many of the rules are codified common sense: Rule 304 - "Look out for pedestrians, especially children, running to catch a tram approaching a stop.", and the rest mostly tell road users what to expect from each other often accompanied by the wording "you should". Those rules don't have the force of law but disregarding them may be used in court to adduce evidence of offences such as careless or dangerous driving.
The new changes are all in the "you should" category. Remember, these are the rules that you won't be automatically prosecuted if you'er seen 'breaking' them. The ones that have the most impact are surrounding where and when you should give way to pedestrians or cyclists, affording them more priority than in previous versions of the rules. In particular part of the new rule H2 says "
At a junction you should give way to pedestrians crossing or waiting to cross a road into which or from which you are turning.". Previous custom and practice was that if a vehicle wanted to turn into a side road and pedestrians were waiting to cross, the vehicle would go first and then the pedestrians would cross afterward. Under the new rule in the same circumstances you should stop and wait to turn into the road and let the pedestrians cross. Perfectly sensible, perfectly reasonable, easy to learn to do. I now do that. As a consequence I frequently get drivers behind me who don't realise why I've stopped, honk a horn for me to get moving, and all because they don't know about the new rules and assume I'm a dullard, not a conscientious driver.
Also the pedestrians don't know the new rules, and often don't cross the road when a vehicle has stopped for them, leading to vehicles working to the new rules stopping to give way, waiting for pedestrians who don't move, and eventually driving off again with the pedestrians still standing there. Or possibly waiting, and then starting to move as the pedestrians also finally decide to move.
The lack of publicity for the new rules has, rather than made pedestrians safer, put them at more risk, increased congestion, and set the seeds for some road rage incidents with uninformed drivers. Good intention - "make pedestrians safer", unintended outcomes - as outlined above. I can only describe it as "pathetic incompetence".
