   Sounds illegal to me.   
      
   70mph is the max in the UK, but only on motorways and dual carriageways (as   
   we so quaintly call them)  - this means that the traffic in opposite   
   directions has a barrier between it, not as some naively think, that the   
   road has 2 or more lanes in the same direction).   
      
   A supermarket car park near me has 5mph signs; I've never seen any vehicle   
   travel that slow, unless manoeuvring into a slot.

   isn't there? if 0.6 is right then pshurely you want to add a half and a   
   tenth.   
      
   Or memorise a table:   
   (80)        130   
   (75)        120   
   70+35+7=112(110)   
   60+30+6= 96(100)   
   (55)         90   
   50+25+5= 80  80   
   (45)         70   
   40+20+4= 64 (60)   
   (35)         50   
   30+15+3= 38 (40)   
   20+10+2= 32 (30)   
      
      
   --   
   Bah, and indeed Humbug.
