Bernard Shaw on traffic controls

[Martin Cassini]

It's unlikely Shaw was thinking of traffic controls, but this is pertinent: "All professions are conspiracies against the laity." Twenty years ago I worked with John Tagholm on a TV proposal called Experts can be bad for you. It challenged the medical, legal and planning professions. For the last ten years, I've challenged traffic 'experts'. Yesterday a traffic engineer suggested I didn't understand the complexities. The complexities of a system you promote? I asked. If the 'experts' harnessed our greatest resource - human nature - instead of concocting complex control systems to thwart it, most of our congestion and road safety problems would disappear - as is happening at the Cabstand junctions in Portishead.
