I've shamelessly borrowed the title from an article in The Economist reporting that Vancouver is banning doorknobs in all new buildings.
The war on doorknobs is part of a broader campaign to make buildings more accessible to the elderly and disabled, many of whom find levered doorhandles easier to operate than fiddly knobs. Vancouver’s code adds private homes to rules already in place in most of Canada for large buildings, stipulating wider entry doors, lower thresholds and lever-operated taps in bathrooms and kitchens.More at the link, and at Legal Insurrection (whence the image).
The rules have provoked grumbling about the nanny state, much of it from doorknob manufacturers... True, elderly and disabled people find it easier to operate doors with handles. But so do bears... One newspaper columnist in the pro-knob camp has noted that the velociraptors in “Jurassic Park” were able to open doors by their handles.
