Guerilla Pot Hole Spraying?

bingo, you said it all, that's the biggest problem with London is that it have a sporadic road network with lots of one-way system (bloomsbury/fitzrovia a good example).

Yes, they're an extremely ill-fitting superimposition on a network that would be far better without them.

let have an example, says New York, we all know that New York have those grid pattern road network, so if a section of road is in dire need of repair, they can easily close that section down and reroute the traffic.

London, being an old city dating back to Roman time (and further), it wasn't designed for motorised vehicle in mind, and notwithstanding the bombing of London during WW2, it still wasn't despite being rebuilt (and already been tarmac'ed), so when a section of road is in bad shape, the best they can do is try and repair the damaged as quickly as possible to avoid big traffic jam the next morning, New Oxford Street is a good example of that, it's a constantly busy road that would cause chao if it shut down to tarmac'ed the entire road.

Actually, the potential drama caused of loss of motor traffic capacity is usually exaggerated. People adapt, traffic finds another way. It's only when people don't know about a change in capacity yet that the main problems arise. It's never quite 'chaos'; it becomes pretty congested, but it never becomes so congested as to stop working altogether.

It's not a question of the council not bothering to fill in the potholes, more of the road network in London not giving them a chance to properly fix the road before the morning come.

London's approach to fixing has not created a long-term legacy of stability. The typical sticking-plaster remedies instead of rebuilding streets with strong foundations means that major streets need to be resurfaced every few years. It's all extremely costly and really doesn't work. The alternative, of course is pretty horrendously difficult, too--London has so many different services running under its carriageways (sewers, electricity, telecommunications, gas, water), basements and cellars extending out from buildings, and other complex subterranean infrastructure, that proper rebuilding jobs would take years in some cases. It's almost a catch-22, but you almost wish that someone would start somewhere and see if the thorough approach is more beneficial.
