I grew up in a town which still had some cobbled streets and though they may look attractive they are very impractical.
Cobbled streets are bad in cold or snow. Snow builds up between the cobble stones and turns to ice which is dangerous particularly for pedestrians.
Having a fall on cobbled streets is also very dangerous. Cobbles not being flat when you fall you have several areas of high pressure which can cause bones to break.
Cobbles also make steering on vehicles difficult inducing vibrations through the steering column as the wheels flip back and forth between cobblestones.
Also when it comes to maintainance cobble stones and paver tend to sink in highly used areas, causing ruts which are very difficult to repair satisfactorily and if your car or van is caught in those ruts it can be very difficult to steer out of them.
So I vote against both cobblestones and pavers for road surfacing in most areas.
