My sister lives in London and i was sure her cistern must be blocked as it was so slow till i realised the bathroom supply was tank fed. Is that just lazyness/cost saving of not wanting to reroute the plumbing? Why in this day and age would anyone not want mains pressure when it's everywhere?
Why is the cold water in some city houses still tank fed?

No it's not, around here the norm is a mains cold water feed to all cold taps. Our tank only servers as a header for the HW cylinder.

Probably just crap in the inlet valve or wrong insert fitted.

very common, if water supply is shut for some reason the bog can still be flushed, with the move to combi boilers this has been done away with , but was the norm back in the day
Plus if cold water is tanked you don't get a neighborhood flow drop when everyone is using water at the same time. Supplier can run distribution network at a lower pressure which has advantages for them.
I live in West London. We lose the water supply 2 or 3 times a year (although it seems to be getting better). With a tank based system we can still wash, make tea and cook so long as the tank supplied water is boiled first. The only thing a higher pressure is needed for is a shower, and a pump takes care of that.
OK I'm rural not urban and have indirect hot water system from the old style tank in roof and vented hot water cylinder.
In the upstairs the pressure from the tank fed hot water is better than the blinking pressure from the cold fed from the mains!
Every now and then the local reservoir pressure maintaining mega-pump fails/trips out or the emergency diesel for it fails to start when there is a power cut (they are regular and getting more regular) and then I get very poor pressure/flow indeed.
So yes as per previous answers a decent sized tank in the loft to tie you over the inevitable failures along with a hot water cylinder are essential in my neck of the woods.

I live in a village, apparently surrounded by decaying water mains. We have "water cuts" several times a year while roads are dug up and mains are repaired. I know this because those of our neighbours who have converted to combi boilers or unvented cylinders post on the neighbourhood Facebook group, asking if everybody else has lost water pressure.
I have a vented cylinder fed from a loft tank (with pumps for the power showers), so I simply don't notice when the water's off. Except for filling the kettle. Which I can do from the hot tap if I have to

An alternative to a pumped shower is to use a hot water cylinder that has a shower coil
Wont work if the mains are turned off
It varies with regional practice.
Shower won't work but until the tank in the loft runs dry. basin will have hot and cold water for washing the person
