Giving way on a hill

I wouldn't be stopping at every bay going down hill. Modern cars are capable of stopping and starting on a hill without any problems so going up a hill I don't expect everybody to pull over and going down a hill I expect to be able to make progress at the same rate as those coming the other way

I was always taught that vehicles going downhill should give way to those going up.

Given that traffic levels on single track roads are usually pretty low, it shouldn't be too much of an inconvenience.

With regard to Rule 155, I wish more people would take notice of the bit in bold...

Rule 155
Single-track roads. These are only wide enough for one vehicle. They may have special passing places. If you see a vehicle coming towards you, or the driver behind wants to overtake, pull into a passing place on your left, or wait opposite a passing place on your right. Give way to vehicles coming uphill whenever you can. If necessary, reverse until you reach a passing place to let the other vehicle pass. Slow down when passing pedestrians, cyclists and horse riders.

You expect modern drivers to have the foggiest idea of their surroundings, ie that they might be on a hill in the presence of other traffic and more amazingly you expect them to use some common sense or put some thought into their driving?

These would be the same drivers who enter a motorway in their 200hp car, and proceed along the acceleration lane at precisely 55 mph, when they get to the end of that acceleration lane they miraculously discover some swine of a lorry driver in the brightest yellow artic ever seen has deliberately (of course hence a swine) been running alongside them at 55 mph with two lanes full of traffic beside him in the middle and outside lanes, and a travelling gap of 400 yards in front of him because he doesn't tailgate...hmm 400 yard gap 200hp, lets think.

Upon finally noticing said lorry appear just at the end of the slip road and amazingly it hasn't been hoisted out of their majestic procession by a passing Chinook, they have to brake hard, this is quickly followed by acceleration Lewis Hamilton couldn't match so they can overtake and come alongside the lorry, make all sorts of signs and gestures at the driver, and then pull in front of the lorry and test out a 44 tonners brakes!!!

And you really expect suicidal lemmings like that to judge the finer points of driving etiquette regarding hills?

Sorry but its all over bar the shouting out there, driving standards in all sort of vehicle have dropped to an abysmal level and i see no sign of courtesy and common sense returning any time soon.
