The fundamental failing is that the ownership of 'stroads' (including those in city centres) is typically with a government entity that is charged almost solely with vehicular traffic concerns. The design solutions are there and obvious for prioritising pedestrians, cyclists, etc. But its impossible to enact these when road authorities are separate to planning authorities. The overarching solution is a structural change in governing these spaces.
