Both road safety & The Highway Code need a bottom up review.
Two rules, 163 & 215 show clearly how road safety is out of date, wrong and thus dangerous.
They are both about drivers passing others on the road.
Rule 163 says, 'Give vulnerable road users at least as much space as you would when overtaking a car'. How vague, subjective & meaningless is that? Different drivers have different ideas so, in effect, this means 'carry on as normal' to each. But the major fault in this is, that at very low speeds, drivers pass other obstacles, like parked cars, much closer, and often only by inches very safely and successfully all the time. So rule 163 makes no sense whatsoever and is utter nonsense.
'Be particularly careful of horse riders and horse drawn vehicles especially when overtaking. Always pass wide and slowly. Horse riders are often children, so take extra care and remember riders may be in double file when escorting a young or inexperienced horse or rider. Look out for horse riders' and horse drivers' signals and heed requests to slow down and stop. Take great care and treat all horses as a potential hazard; They can be unpredictable, despite the efforts of their rider/driver.'
