Bike friendly cities are converging towards 30 km/h. Kph, mt, sec: are all widely used but wrong.

  As an example (for GP) many London boroughs (city councils/districts) now enforce a global 20mph (32kph) speed limit on all their roads. With recent legislation making it trivially easy for boroughs to do this (I think it used to require consultations etc, but now they can be unilaterally applied with consultation with the public). Additionally TfL have had the entire of central London (within the congestion zone) 20mph.
