they spent so long trying to make amends
Did they really though? They worked to appease their guilt but never really dealt with the underlying reasons it happened in the first place.
Most of those that did the dirty work during ww2 just went home after and carried on.
Same with the British. Most people have no idea about how or why all the shit in the middle east started or why it continues.
Not just bumps but designing infrastructure so it forces the drivers to negotiate it at lower speeds.
Simple stuff like narrowing the approach to junctions and roundabouts so it has to be taken at a slower speed than it being a wider aperture when minimal braking is required.
Raising the pedestrian or bike where it crosses a road (on side streets) so the vehicle has to slow rather than the active transport methods.
Reallocating road space to wider pavements and segregated bike lanes so streets are mixed modal.
