A pedestrian in an urban setting should not have to "look properly" whatever the heck that means, when walking about in a SHARED PUBLIC SPACE they should expect to be able to walk where they want in safety. That they cannot, and indeed probably ought not do so, simply shows what an effed up topsy-turvy urban environment we have allowed ourselves to create in our on going love affair with the almighty motor.
Urban shared spaces were originally, and in the main, and putting aside some ghastly 20th C aberrations like urban dual carriageways, created for people, not for their vehicles. Else why do most of our urban public shared spaces still retain their pre-motor-vehicular street patterns?
That so many folk think otherwise is
a) conclusive proof that lead induced intellectual impairment is widespread and persistent
b) ignorant of history
c) evidence of the triumph of the very barbarism that city life, civilised life, was originally intended to overcome.
