   This will be more of a problem for some, depending upon where you live.   
      
   My car uses a combination of satnav map data which includes the set   
   speed limit on each road, plus the output of the camera which (attempts   
   to) read speed limit signs.   
      
   Since the default speed limit in Wales was reduced to 20mph, the speed   
   limit displayed by my car has been wrong more often than it is   
   correct[1] - and not just reading "30" when it ought to be "20".   
      
   At the moment that is a nuisance.   
   If that same incorrect data is to be used in the way described in this   
   thread, it becomes far more than a nuisance.   
      
   [1] In a 8 mile radius around my home, I am not exaggerating when I say   
   "more often wrong that correct". - and yes the satnav's mapping data has   
   been updated twice in the year since the limit was changed.
