Not design. There is lots more friction in a PS rack than a non PS one. Which the assistance overcomes.
And they were all heavy to steer and even more so to park. I've owned many.
With very low geared steering and large steering wheels. But still hard work.
Does on mine.
On mine, you'd have to have failure of the brake pedal since the master cylinder is in two parts. Each part feeding an independant brake circuit.
Some may, some may not. Not all are split front to back. Some diagonal. On my SD1, one circuit feeds four pistons on the front calipers, the other the other four plus the rear brakes.
It depends on what reliability means.. The computers in telephone exchanges have faults more often than a normal computer, however they still work unlike the normal computer. The same applies to the brakes, more components means more faults but the brakes should still work. However you have to get them fixed as a second fault may well cause total failure.
Its high availability, with reduced reliability as a consequence.
A friend of mine had a company car that cut-out suddenly on a roundabout. The garage said there was nothing wrong, but a week later the same thing happened and he hit the kerb, wrecking the suspension. They finally found a damaged wire that was intermittently causing a problem on right-hand turns.

You are forgetting the different gearing. I don't know current ratios, but one set that I do remember from the 80s was non-PS 4.15 turns lock to lock, whereas a PS rack was 2.1 and that makes a big difference. On top of that, the PS racks are a lot stiffer when not powered, making a failed PS setup extremely hard to turn, the PS is usually standard on the heavier models with wider wheels and smaller, sporty, steering wheels may be used. I know that at low speeds, my wife would be totally unable to turn the wheel on my Focus 1.8 TDCI if it weren't for the PS.

Just about any car parts shop. Even Halfords.

Perhaps I explained it badly. Have you tried a power steering one with the power assistance not working? That is *way* heavier than the non PS version - even when the gearing is similar. Due, I assume, to the friction of the seals, etc.
A propshaft driven second pump was common once upon a time. But I dunno of any modern auto with one. Last car i had with that was a '67 P6 Rover
2000. The 3500 version - with nominally the same B-W 35 box didn't have one.Not a good idea to tow start such an auto - it will likely run into the tow car when it starts. Push starts were recommended - you'll sometimes see this in old US films.
Pah. Wait until you have to drive a towed car with mole grips in place of a steering wheel.
Why would you want to do that ?
Every schoolboy comic tells you that if the steering wheel comes off you just push it back on the splines again
I did gewt towed halfway across Wales when my Enfield broke down and bugger me, if the bastard thing didn't fire up as son as I got it home
And if the steering whelk is missing?
A mate's big dumb brother pushed a Vespa 150 for ten miles home. When we looked at it, the wire to the coil had come off.
Mole grips? You were lucky!
You need to try it with reins lad! When I were a nipper, I had to drive the steam roller home from Halifax every night, and getting beaten with a wet kipper all the way back. A plate of crushed asbestos for supper, and we thought we were lucky.
It can be done, at least on a basket-case student Renault 5 (I think that qualifies as my "most worried moment as a car passenger"!)

The traditional form of this is to wake up a sleeping front seat passenger and agitatedly hand them a steering wheel with the cry, "It's come off!"
It takes them _ages_ before they realise you're still using a perfectly good one that's still attached, and that you've thoughtfully brought a spare with you...
Also works for handbrake levers when parking on hills, or the advanced form can use a distributor cap or brake fluid reservoir when already blasting along a motorway. "Oh, this fell off at the last services"
It was perfectly clear.

Unless the wheel cylinder leaked and pissed brake fluid all over the shoes ....
Can't speak for all, but saw a Jag (XJ40 ???) which had a rear disc foot brake, but the inside of the disc formed a drum for the handbrake with separate shoes
A comment our MOT tester used to make when I saw the difference between the foot braking force and hand braking force ...

Being charitable, maybe the poster has confused the fact there exists signage in the UK for minimum speed limits, with the existence of such things ?
Been there, done that, had the AA Relay van turn up without having to have a patrol check it really wasn't a roadside repair first.... (It didn't just leak a bit past the seal - the casting had cracked.)
Some have a diagonal split, so that wouldn't make any difference.
