In some countries, there are, in addition to mobile and fix speed cameras, some "almost-fix" speed camera : these speed cameras are placed on the roadside for a period of several days (one or two weeks) before being moved elsewhere for the same duration.
It would be good in WME to provide these types of radars with an estimated duration (and for example to cancel them if there ane any confirmation during a period of 24 hours).
With the present system, police alert are to short and fix camera reported in WME is not the right solution.
